I think not... I think it was more about sincerity. Like the seme can't force dongbaek to love him and that they die if he tries to force it how he did the last three times and I think there was something about it the time they were shot.. that dongbaek wanted to tell him "I love you" but then got shot there or so... Or I'm completely off now.. I'd have to reread it completely but I don't think that saying "I love you" will kill them (there was no such rule)
WAIT OMG WAS THERE STH LIKE HE'LL DIE IF HE TELLS HIM "I LOVE YOU" or I just mistook it with a different story-?
I'm not sure anymore I have 1000 ongoing mangas
