Imo I feel like the twink might have some unrequited feelings for ml that's why he still keeps him around as fwb. I bet when he actually find out that mc and ml are a thing, he's gonna be so bitter because he wouldn't want ml to be "owned" by someone (especially not nanjo, his plaything lol)
OR he doesn't care cuz he's a hoe

I thought it was only me seeing things, but I'm reading some comments, and I think Seonhwa really did have a sus look in this last chapter, and the way he left like with a mischievous smile, I think he maybe saw them together, or he read one of Nanjo's texts to Mokyeon, idk, but think is he knows what they're doing behind his back, and he wants his revenge. Revenge on Mokyeon of couse because Nanjo has all the moneyyyyy
