tbh nanjo doesnt owe anything to mokyeon, he doesnt need to like him back. mokyeon was quite a jerk to him throughout the whole story. if he wants to be manipulated by Sunhwa, that's his business. I think sunhwa is annoying, but hes not entirely wrong either, like nanjo is a grown ass man, he could easily realize he was being used, but he doesnt seem to care about it either lol. mokyeon only fell in love by himself and now realizes he messed up with the guy he likes, and now nanjo doesnt need to reciprocate his feelings at all dude. like man, own up to your own mistakes, change and win nanjo's heart genuinely (I hope thats what he will do and not just be crying and playing the victim lol )
guys I'm dumb what is the ring deal again?
He wore a ring at the start to fake being in a relationship, and I don't think he ever told the boss guy the truth
