there are things that best friends do. like studying all night long and then falling asleep while leaning on each other. or holding the other one while he cries.
and best friends also tell each other to keep going after they lost a vball game.
but daichi isnt sure if best

friends also lean their foreheads against each other and stare into each others eyes to feel better and calmer after a lost game. and best friends also dont start sleeping in the same bed bc the room is cold and they wanna hold the others hand.
best friends dont dream about

kissing the other one. so when he wakes up one night, sugas smiling face still on his mind, daichi thinks that maybe theres something going wrong. maybe it's just a one time thing, dreaming about kissing your best friend doesnt mean anything, daichi decides. it doesnt

mean anything until daichi stands next to suga who makes a dumb joke during their break and daichi can only think about how nice his lips look, how much daichi likes it when suga smiles. how easy it would be to lean forward and just kiss him.
best friends dont think about

kissing the other one. best friends dont think about dating the other one, daichi has to realise a few days later. daichi sucks at being best friend.
he thinks about all kinds of ways to confess to suga and about all kinds of ways suga could confess to him.
but they stay dreams

because they're best friends and best friends dont confess their love for each other.
but there are days where he realises that suga also sucks at being a best friend.
when suga doesnt stop smiling after they already leaned away from their forehead touches or when he holds out

his hand for daichi to take it and doesnt let go for some time.
but maybe neither of them sucks at being best friends daichi thinks when sugas looking at him one afternoon. maybe they're just best friends and a tiny bit more than that he thinks when sugas mouth is so close that

daichi can feel his breath.
best friends don't kiss each other but suga and daichi do. they kiss and daichi thinks that this is better than his dreams.
best friends dont kiss but boyfriends do and daichi decides that nothing is better than being sugas best friend and boyfriend
