He is your best friend like... since you guys can remember, probably since you guys have 10? maybe...he was kinda reserved but of course he open up with you... you were his best friend after all. .... He's emo.... kinda tsundere.... he is kinda insecure but always pretend to be cocky, but with her he can open up, he can let himself be vulnerable... she was with him in his happiest and saddest moments... she never leave him behind... she always stayed and support him... it was normal he end up falling in love with her... right? .... Today you guys were in his place, plying video games and drinking a little (too much), finally it was your turn to play, he lay his head in your shoulder because "he was dizzy", he probably was falling asleep... or was already too drunk (he isn't a good drinker) because he was starting to mumbled things...
