Dongho won't cheat on the seme. I think that they think he is cheating because he was looking in front of the mirror with a lot of hickeys all over his body. But it was just a flashback cause it's Jae hwan who gave him all those hickeys
He didnt, the glasses dude is interested in dongho if im not wrong but dongho doesnt seem to think of him in that way ╮( ̄▽ ̄)╭ anw the latest chap jaehwan and dongho made up and had sex alls good for now no trouble YET
Spoiler warning :
he cheats...
