It’s not cheating if they’re not dating but I get what you mean Niki
If the main couple are involved with each other romantically or even just sexually and one of them do it with some 3rd person becuz they are not "official" yet then it feels cheating even if it's technically not and I hate it SO MUCH
Guys please someone tell me if the uke will have sex with the other guy? I don't wanna see that I love seeing the mc and ml together
