Well, i guess because all he cares about is sex. that is the reason the threesome got started in the first place. As written in the creator's notes ( his profile) he hates vers and so nanjo being a bottom is huge no to him. Plus, they did it behind his back and almost suffocated him lol. So i can understand why he should upset for certain point.

I also don't get why he's so upset. He was literally already cheating on Nanjo with random guys. And he never even liked him in the first place, he just pretended to be sweet and innocent while treating him like a wallet.
And they even said in the past Mokyeon and Sunhwa were friends with benefits who would cheat on their boyfriends to sleep with each other.
Sunhwa knows Nanjo is still hung up on him and doesn't like Mokyeon, so it's weird that he saw Mokyeon fucking him (during a threesome btw) and act like his one true love got stolen away lmao
