If y'all wanna know: - - - - - (Spoiler alert)(may not be accurate due to google translate) The Seme didn't cheat. The other guy/supposed side dude, was the one who blackmailed him into faking an affair and breaking up with the MC. I guess it kind of shows in the Seme's text replies, despite it showing affection in the replies, it's usually short sentences to get it over with. I assume the Seme still really loved the MC, and that's why he never wanted to be the one to break up with him, until the MC "found out." I can't remember what the rival did for the blackmail thoug
