my headcanon is that seo in fantasises about MC's sturdy, muscular body from all the judo he did! i defs believe him when he says he couldn't take his eyes off of MC during his fights. besides from being in awe of his judo skills, i think he probably also got hot and bothered by MC being all sweaty and making sexy expressions in the ring. but MC is also surprisingly kinda pure? his puppy like eyes are so cute! my imagination is running wild LOL but defs understand why MC would be his standard

It could be that who he sleeps with isn't necessarily his type. It could be he likes YeongWoon anyways, or else he's just in denial or doing the opposite of.
Also...when YW said "maybe pretty ones are just his type" were not sure since....Seo-In slept w/ Hae-Yool to flush out HaeYool's sponsor (who turned out to be his cousin and president of All One Entertainment, who may or may not be another kink in development), and the guy that Seo-In kissed was his brother so....unless there was a third guy??? That also looks like those other two?!? Those were the only two we saw for sure...unless there was a third guy I didn't see who also falls into those "pretty guys" category.

He did taekwondo. I think judo is a Japanese martial arts. Taekwondo is a Korean martial arts.
I'm not sure about the sweaty and manly expressions in the ring. They were middle-schoolers....that's when they first met.....and then ten years have passed so....they were just kids back then....and now YW has stopped doing martial arts since probably that long ago....either from that incident or maybe w/ his father.
this seems interesting and i like that it feels like seo in has wanted MC for a long time
