Even only reading it making me sick to my stomach.
I hope Sunghyeon saying "the last time" would mean that once he knows that Daon scre**** Jaemin he rests his case and moves on. Dude needs to see that he deserves someone better.
I hope Daon's not gonna get ending like in Scum's Wish where the dude takes the cheating beesh openly even gives her permission to cheat even when she's married to him as long as the beesh tells him each time she cheats.
