To kill you with a kiss// To steal you with a kiss: Complete 9 chapters. Kyungsoo used to have a crush on Jongin and now he is his new roommate (that he sleeps in the bed with), but Jongin thinks Kyungsoo is straight

Next Door:
The things I wish I could say: one shot. Kyungsoo has a crush on Jongin and follows his around (they live across the street) and he doesn’t think Jongin knows. However Jongin has been putting on a show for Kyungsoo, but he goes a little far and scares him off
Neighborly encounters: one shot funny. Kyungsoo moves into a new house next door to Jongin and tweets about how hot Jongin is
iridescent (say that you’ll love me only) : one shot. Jongin moves across from Kyungsoo and doesn’t like him, but Kyungsoo has a crush on him.
Clueless and annoying: ongoing. Jongin has a huge crush on Kyungsoo, and circumstances has Kyungsoo moving in Jongin’s house
Stay with me: one shot. They are neighbors who were already dating in this case, and when Jongin’s abusive family becomes too much he runs away to Kyungsoo
Thank God that SHINee is still consist of 5 boys since 2008. If they're not, I'm just completely done with SM. I love them way too much because they're still together. And please make it forever. ♡
