Well then : we're in a flashback triggered by a guy telling mc he look exactly like someone from the past and he is just replacement for that person. ml and white hair guy were in middle school (they don't look like it at all but whatever) and white hair's mother hired a tutor (no idea if he was in highschool or college) white hair guy fell in love with tutor immediately. Cue current chapter.

Ok I'm so lost whose the bloke that dying and he's a middle schooler?????
