so i've read this manga before but i forgot what it was called. it was about this couple who are completely opposite of each other. one is a quiet person while the other is somewhat of a party-er and stays out late and if i recall correctly he also sometimes cheats? on his lover ..the quiet one can't leave his lover because he loves him too much ..i don't remember the rest but i know at the end the roles are somewhat reversed with the quiet guy (did a transformation) and staying out and calling on his lover to come pick him up ..idk if that makes any sense at all .. it might be a oneshot i'm not quite sure ..
thanks though!
