I think what mc feels towards kijun is guilt not love. Like yes he liked him but at some point you fall out of love with people that do this shit to you but he feels guilty about moving on from his crush... I think he feels obligated to repay him by liking him forever... but he enjoys his time with kihyun even though it started as a substitute and the line is still blurry it's still kihyun and his actions that he enjoys but they're goddamn twins so it's so messy and hard to differentiate... that's why you don't mess with families and people that you work with and things like that because it's gonna fuck up your life ...
Honestly I'm not sure if kihyun even has a chance but I really hope he can move on from kijun... and i hope this isn't gonna be torturously long for it to just end in some stupid way
Irl it'd be impossible to stay with either of them unless the brothers never see each other again or something because how you gonna look them in the eyes after fucking them? But i don't know how the story will progress... throuple maybe?
