I thought they were good friends though.. they spend birthdays together, they have mutuals and go out from drinks and stuff and also share everything since they’ve known each other for years. I mean it’s clear they don’t have the best personalities but they’re still friends that goof around from time to time
Lemme just give you two examples of how much friends they are :
1. Remember that Banana earrings that Mokyeon teared off bloody from his ears . Did you see sunhwa asking about what happened to you ? Why you hurt yourself like that ? Or any follow up on how his friend is doing to self harm like that ? No he didn't.
2. In chapter 33 , when mokyeon came to his house with his face battered, his one eye almost gone due to beating, did you see him applying any kind of medicine? Or suggestion to see a doctor . If he wasn't in relationship with Nanjo and it wasn't that deep , he should be genuinely concerned about his friends bad conditions. But nop there is nothing like that .

Mok is such a fake friend bro he pmo baddd. He first screws his friend’s fine shi behind his back, attempts to call and make up w him through his friend’s phone and then meet up and reveal his friend’s intentions from the beginning
He’s so messy
