#like my sweet summer child youll always be baby even as the eldest

[kewpie-aisle]

Daichi is the eldest in his family with four younger siblings (canon), with four younger siblings. Which really all adds up to why he's so...the definition of responsible. But that got me thinking to a different direction he could go... Eldest!Daichi who was taking care of his baby siblings while he was a baby too. Learning how to change diapers and help his mom rock the babies back to sleep carefully.

Eldest!Daichi who learned how to cook early so he could help make breakfasts and lunches for the kids so his parents wouldn't worry.

Eldest!Daichi who went to all his siblings sports matches or sat down to help with their homework since he went through the grades first.

Eldest!Daichi who taught all his younger siblings how to ride on bikes after taking the training wheels off. Promising them he wouldn't let go and he never did. Until they were fully balanced and off on their own. Eldest!Daichi who felt like he could never be weak or unsure in front of anyone. Especially because he was also the strong one in his friend group and needed to be there to take care of them. Eldest!Daichi who hated being called the "dad" of the friend group but didn't want to say anything to anyone. Because he didn't want them to be hurt, even though he hated the joke. I mean he's just a regular high school kid like them.

Eldest!Daichi getting into his first relationship in college and it getting serious really quickly. But things ending badly because his partner wanted kids and Daichi put his foot completely down. Eldest!Daichi holding strong opinions against having kids because he knew what a large sacrifice having them actually was. And he didn't feel ready just because he was getting older. This ended up being a pretty big thorn in most of his relationships. Eldest!Daichi not knowing what being taken care of meant until you came into his life. Someone who finally fought him to say love is about being there for each other not just handling everything.

Eldest!Daichi feeling a love he's never felt before watching you immediately get along with his siblings and seamlessly fitting into everyone's life. Being shocked when you see he has his hands full with the youngest ones so you get up to go pick up the others from a sleepover.

Eldest!Daichi watching you bond really well with his younger sisters, giving them really good advice as they navigate being pre-teens and teens. He would take pictures when all three of you decided to match, making that his phone wall paper.

Eldest!Daichi listening in shock when you share stories about how his mom was apparently always worried about him when he was young because he got sick often. How she would make his favorite dishes and that she was nervous to have more kids in case it took away attention from him but that he was such a perfect kid. He had completely forgotten those memories. Eldest!Daichi coming straight to you for cuddles after having a particularly bad fight with his younger brother over something ridiculous. But he had accidentally said something really harsh. Hearing you out when you said to make amends because that's family. Eldest!Daichi being more honest and leaning on his family more whenever he needed help. Because every time he needed someone you were always there to catch him. Reminding him that he's human and needs his people. Eldest!Daichi re-thinking all his life decisions watching you wrestle with his nieces and nephews during a family party. The sight of you blowing raspberries on his niece's belly and hearing you both giggle sets off every nerve in his brain.

Eldest!Daichi making a mental note that he likes some nicknames, when he hears you moan out Daddy real sweet into his ears. He's got your legs hooked over his shoulders, pushed deep in you. Hand over your stomach pushing down where he feels his tip hitting. Gasps of asking for more spilling out of your sweet mouth. He's still got time before becoming a dad for real but no harm in practicing until then.
