There's this one BL manhwa about a boy with red hair that sees this black haired guy and they meet eyes and the red haired has this like " that's so raven" moment, in where he sees himself fucking with the black haired guy,i also remember that both of them are in college. I also think that what i just described is only like,the first chapter? I was gonna read but then i accidentally closed the tab and never found it again (╯︵╰,)
