yea. it's a seemingly mutually beneficial relationship they have, that is sleeping with each other for so long, cheating on their partners with each other etc etc but sunhwa hasn't actually done anything that actively harms our mc and meanwhile our mc was trying to sabotage sunhwa's relationship the whole time lol
I mean sure, sunhwa's relationship with nanjo was hurting him but how tf was sunhwa supposed to know that

I know everyone hates Sunhwa and I don’t like him that much either but I feel like his annoyance with Mokyeon is so valid. Dude had a crash out at his birthday party, started fucking the guy he was seeing behind his back (and sounds like it wasn’t the first time) and to top it off, he didn’t even go to his house to apologize, but to ask Sunhwa to contact Nanjo for him. You can’t say what you want about Sunhwa but the truth is that him and Mokyeon have been friends for a long while and Mokyeon seemingly doesn’t give a fuck about him lol
