You were seven when you were introduced to the twins. Coming from a foreign land, you struggled with the language they spoke in, but they were patient with you and taught you their language and much more. The twins were multilingual and explained it was from their frequent traveling and relatives from different places.

You and the twins were close, but Lumine spent more time with you, making Aether whine a lot. He would always poke sticks at you and hide your legendary, full art Pokemon cards to catch both Lumine's and your attention. It does work, but Lumine's mad.

"Aether!" She'd scream with a lisp because of a missing tooth. "Stop doing that!"

Oh, but Aether is a sibling, meaning he'd play the 'innocent' card. "Stop doing what? What am I doing?"

In the end, you'd always have to call their parents when they fist fight at the sand pit. "Aether and Lumine's mom! They're fighting again!"

"Again?" The tall blonde sighed. "Thanks for telling me, hon."

After a good scolding, Aether and Lumine would be totally okay the next minute like nothing happened. You were used to their banter and rightfully took your Pokemon cards back. Lumine stuck a tongue out, blowing a raspberry at Aether when he turned his back, grabbing three large sticks.

"Fight me!" He cried with glee, giving one stick to his sister and one to you. "I will be the grand king of the sand pit!"

You vaguely remember the rest. Maybe you lost the 'sword duel,' or maybe you didn't, but what you did remember was this tall kid playing with his cat and eating the sand. Forget the kid, the only thing you remember is his cat's name called Azhdaha.

Your hands close your story book. You would never admit to your friends, but Lumine and Aether that you still read fantasy. The other kids in the neighbourhood would laugh saying what you were reading is a kid's story.

"So what if it's a kid's story? If you like it, read it," Lumine says aggressively while Aether opens the door for both of you.

"Lumi's right. They think they're all grown up, but they're kids too," he closes the door behind him, waving goodbye to your grandma rocking on the porch. "What's the story about anyway?"

You walk ahead, leading the two to a local mall. Every week, Aether, Lumine and yourself would spend Fridays and Saturdays together.

You and Lumine often joke how Aether doesn't do 'Saturdays are for the boys.' To which, Aether would scoff and reply with, "Boys who say that are stupid, not all but most. Saturdays are for spending time with people you care about. I don't care if they think I'm weak."

You step foot in the bus, tapping the card to pay for your admission. The twins, walk behind, doing the same and sitting next to you on the bus.

"It's called 'Songs of a Siren.' It's cool, you should check it out." You say, scooting a bit closer to the side so Lumine could have more pace to sit. The bus is packed. Teenagers littered inside, only a few adults were there including the bus driver. "Let's leave. Teenagers stink."

"...But you are one."

"Well-"

After the next stop, you push yourself through the crowd, trying to exit. Lumine pushes people, muttering a few 'excuse us' while dragging her brother. Your feet land on the concrete sidewalk and you finally breathe freely.

You see the twins finally get off the bus and tilt your head, "Let's go, the mall isn't gonna wait for us."

Entering the mall, the first thing you pass by is a clothes shop. You and Aether share a look, quietly doing rock-paper-scissors behind Lumine who's beaming to go inside.

Rock.

Aether chooses paper.

You droop to the floor because you're dramatic, knowing that once you go in the shop, you'll be the one carrying Lumine's purchases.

"Alright, Lumine," you say sighing. "Let's go shop."

You see Aether in your peripheral vision, pumping his fist laughing a quiet, "Yes!" when Lumine takes out her wallet.

"I know you did rock-paper-scissors." She counts the bills from her wallet, "But I'm buying for Aether which means even if you carry the things I buy, Aether's gonna have it much worse because he will be trying on everything I tell him to wear." She grins, settling with a black debit card.

After hearing this, Aether tries to walk in another shop to avoid dressing up for Lumine, but his sister quickly catches on and pulls him by the ear and walks in the clothes shop.

"Let's go!" She says to you, "These clothes won't shop themselves!"

...

"This one?"

"No, you look like grandpa in that outfit."

"Well what if I like looking like grandpa, huh? What are you gonna do about it?"

"Some people can pull off the sexy grandpa look. You're not 'some people.'" Lumine pulls out another outfit from the rack. "Try this one," she laughs, seeing Aether's horrified face and pushes him in the dressing area.

This is the ninth clothes shop you three go to, and you were starting to feel bad for Aether who had to wear every outfit Lumine wanted him to wear.

"Lumi," you say calmly, having trouble holding five shopping bags on each arm. She's on a shopping spree and you wonder how she gets all the money to buy these things. "That should be enough shopping for the day. I'm hungry."

The blonde lifts a hand. "Hold on a second," she smiles before banging on the changeroom door, "AETHER LET ME SEE THE FIT."

You can hear the loud sigh from the other side of the door as it slowly opens. He only peeks his head out, shyly mumbling, "This is embarrassing. I don't want to walk out like this."

Lumine rolls her eyes and pulls the door open, revealing Aether in a white dress shirt and dark pants.

Aether lifts an arm, inspecting the design. "It's a bit..." he pauses, thinking of a way to not offend his sister. "It's not my style." His eyes seek for your help to back him up, but you couldn't. The style on him looks so ethereal to him, and Lumine has the same idea.

His twin ran up to an aisle and picked out two accessories: a silk cloth and a floral pin. Lumine shushes Aether who tried to punch her.

"Shut up Aether, you'll look great." She pins the black rose onto the front of his shirt and ties the silk cloth around his neck. She steps a few steps back, making a rectangle shape to symbolize a picture frame and elbows you lightly. "He looks okay for once."

Okay is underwhelming, but to describe Aether better, he looks celestial. The warm studio lights hug every angle of Aether from head to toe. His golden eyes seem to brighten more and the outfit only accentuates his physical traits more.

From the corner of your eye you spot a tall-ish man who has been wandering past the same aisle but never picking anything up. He wears ordinary clothes- a T-shirt and jeans (rather stylishly), but you know from his incoming aura he's more than just an ordinary person.

You tap Lumine discreetly while still holding onto her shopping bags and tilt your head towards the man.

Aether, who keeps picking on the cloth around his neck goes frigid when the strange man walks up to him.

"Hey kid," he says cooly. He looks Aether up and down, lifting his shades to see clearer, and pulls out a small business card from his pocket. "You look like idol material. Ever thought about being a part of a boyband?"

Out of politeness, Aether takes the card and laughs nervously, "Not really" He looks at Lumine and you for help, but you two pretend to not know him when he turns to you.

The man shoves his hands in his pocket, blowing a bubblegum and popping it. His hair slightly tousles when he turns, waving a hand.

"If you ever do decide if you wanna be an idol, auditions are held next week at 10AM," he saunters off. "If they ask who recruited you, tell them a man by the name of Valentin did."

His lavender irises looks back once more before leaving the store, "The people from Teyvat Entertainment are introduced by my very hands. Don't disappoint me."

The automatic sliding doors open for him and he waves the store greeter a goodbye.

You see Aether's eyes scanning over he card Valentin gave. His lashes flutter quickly, signaling you and Lumine he was either shocked, or confused.

Lumine grabbed the paper, a habit she picked up due to being a twin and having to share everything with Aether who won't share. Her lips part, showing the card to you.

Teyvat Entertainment.

A company who created the world's famous DCKZ and the idol, Barbara. Teyvat Ent. has one of the youngest, top rookies of the year because of a group called TVT Dream. A company with many celebrities' and the business card is legit.

A store worker no older than your age meekly walks up to the three of you and asks, "Hey, uh. Are you ready to purchase your clothes?"

...

Aether shoves Lumine (don't worry she shoves him 10x harder) on the stairs while you watch from a safe distance.

You wave hello to their mom before waltzing into their home like you did many other times. You were their third child in their mom's eyes.

You slam the twins' room open and lay yourself on the bottom bunk of their bunkbed. "So do you wanna check Teyvat Entertainment?"

You fish out your phone from your pocket and hand signal for Aether and Lumine to come close to see. Your phone turns on, showing the lock screen of the twins in their embarrassing toddler moments then unlock it. Quietly laughing at the twins who have their faces beet red from the photograph.

"Why do you have that pic? DELETE IT."

"Did mom give that to you..."

You ignore them, opening up Google and typing in the Teyvat Ent. website and search their contacts. You ask Aether for the business card, comparing the two numbers side by side, and Valentin is indeed one of the scouts for the company.

You shut your phone off, hugging the two siblings together tightly. "Whether Aether decides he wants to be an idol or not, we'll still be the best of friends."

Lumine grins, squishing your cheeks, taking a closer look at you. "Well, duh. Are you scared we'll fall apart? No, if anything you should be scared we're never going to leave you alone even if you're 60 and married."

You pinch her cheeks and start to say something until you hear sniffles and coughing. You turn to Aether who was hiding his tears.

"Shut up, I'm not crying." He harshly wipes away the water falling from his eyes, "When I go famous, I'm going to give you my autograph so you can sell it and eventually get 20 cars and houses."

...

You were a teen when the dark-haired Valentin scouted Aether to be a trainee in Teyvat Ent.

You note that without Aether, their home is extremely quiet. It's odd not seeing Lumine scream at Aether for taking her hair clips. It's odd not seeing Lumine aggressively pull on the colourful flower hairclips on Aether's hair, just to get the clips back. It's so odd not seeing Aether is general.

Lumine scrolls through her phone, looking for furniture to add to her new apartment she shares with you. The only thing in the newly bought apartment is three mattresses, three plates, and three cups, just in case Aether visits. Though, Aether visiting is rare. His visits only happen during December for Christmas, but even then he had not visited. It's been two years since you and Lumine last saw him.

You stare at your last sent messages to the blonde boy.

▶ hEY. (threatening)

YO

▶ take care okay? lumine's worrying all the time for ur health bc she keeps watching yt vids on how idols over-do themselves from training

haha thanks for telling me

the last thing lumi sent to me was "FUCK YOU"

▶ well the last thing you sent to her was "U BUTT"

▶ and she took that seriously

are you siding with her?

▶ yes

oh okay, frick you too seen three months ago

Your feet pad against the wooden tiles, grabbing a glass of water while scrolling through twitter. You lift the glass to your lips and almost choke from the water you drink.

You click the link on the phone with the title "Debuting boy band already claiming the hearts of many! Please welcome 4nemo!" Four boys stand in the picture, one being Aether.

You place your glass to the sink and run to Lumine, sitting next to her and who her your phone. She reads it over and visibly shakes. You swear she was about to cry until she takes the phone from your hand and starts throwing it, "AETHER THAT BITCH. HE DEBUTES AND SAYS NOTHING."

You're mortified and pull your friend away from your phone, "THAT'S A NEW PHONE, STOP." You push her away and run to your device, clicking on the link.

"One, two, three! Hello we are," Aether, the familiar blonde says.

His group members follow after him. "4nemo!" They say in chorus. One by one they start introducing themselves.

"Hi I'm Aether!"

"Kazuha," one says with a raise of a hand.

An energetic member steps up with a grin, "And I'm Barbisabeto!"

"He's Barbatos, forgive him." Teal undertones make it's way to the camera, "Hello, I'm Xiao.

The one with twin braids step up, mischievously grinning. "Please take care of us and support us during our journey through the music industry."

His teal eyes squint behind the camera, whispering to the member behind him. "Psst, Xiao. I can't read I'm blind."

Xiao rolls his eyes and steps up, slightly bowing, "Please support our debuting group, we will see you in our music videos."

But Lumine and you never paid attention to what they were saying. Both of you just started crying insults of endearment to Aether because he looks so... different. His face had mature and he's a real idol now.

Reality sinks in.

Now that Aether had a growing fanbase, it's going to be harder to contact him.

"Lumine, how are we going to talk to him now?"

Lumine ponders a bit, resting her chin on her hand before smirking. "Let's create an Aether hate page."

"Yes, let's do it."

After a quick recording of Lumine and yourself, you posted the video online, and soon enough, it goes viral.

Lumine laughs, replaying the video.

"This one's for the boys with the booming system," You say monotonously in front of the camera like what you said was a speech instead of a song. "Top down, AC with the cooler system."

Lumine comes on screen, flipping her middle finger at the camera. "When he come up in the club, he be blazin' up. This one is actually not for the boys with the booming system. This is for the BITCH, AETHER WITH THE BLONDE BRAID. Look at you with your ugly ass smile," She speaks in one breath and it amazes you. "Make sure you get millions of hits or it's all for nothing. Oh Aether's an ass."

The screen shows your hand scooping the phone up and waving good bye with Lumine still dissing Aether.

You nudge Lumine, showing a comment written at the bottom of the video, covering a laugh.

"who's aether?"

"huh??! aether?"

"lOL Why Does The Person On The Left Look Like Aether?"

"OH 4NEMO DABUTE. SHUTUP YOU ANTI. THEY'RE GORGEOUS. YOU'RE THE ONE UFLY" ➡ "ahisfdh you obvi didnt watch the whole video. she said "make sure get millions of hits"

Lumine grins, commenting at the people calling her ugly and Aether way better looking. "Lol, IKR. the one on the left is trying too hard to look like Aether. it's like shes tryna be a twin or smthn"

Though, because of your viral "hate" video, 4nemo's popularity sky rockets because of the unknown 'Aether' of the group.

...

Aether watches the video on the news channel, because that's how popular the video got. He looks at his manager, "Can I send a hate video back?"

"Aether, no."

But the winds are troublesome as the ocean, because a boy with teal tips on his hair snatched the managers phone, running and giving it to Aether. "AETHER. DO IT RIGHT NOW."

...

It was a shock to you seeing people follow your twitter account.

"LUMI, [NAME], IM SRRY I LOST MY PHONE AND DIDNT WANNA TELL ANY1 OR THEYLL GROUND ME," said the tweet, tagging you in comments.

Lumine doesn't have twitter, so when she looks over your shoulder seeing the tweet with her name on, she grabs the phone and locks herself in the bathroom, "R U FR AETHER?U DIDNT REPLY TO MY HAPPY BDAY. WE SHARE A BDAY DUMBASS"

She calmly unlocks the door, giving your phone back casually while you whine, "Lumine! This is twitter! They're gonna cancel me!"

"I'll cancel them back."

Ding! You receive a post with you name under the comments again.

hello, i have to apologize for our member stealing the manager's phone to tweet that. i swear that kid's the most responsible, but he's been triggered. #kazuha

You quickly type back, under the hashtag 'kazuha.'

"@/4nemo sorry uh thats one of ur members twin & shes mad that aether never gave her a bday present when she gave 1 to him #kazuha"

notes: psst here's where i got aether's outfit inspo when they were outfit changing at the mall
