Ahhh is this one of the first times we're seeing Yoon finally start warming up to Vasya?? Not just giving in to physical pleasure but actually Vasya as a person?? I mean it might be because there's something he's more scared of than Vasya but still!! I'm so excited for this development!

Yeah, they're each finally having a chance to see the real person underneath all of each other's pretenses. Till now Yoon was still convinced he kept being only the newest favorite toy for Vasya, but now seeing Vasya genuinely getting worried at seeing Yoon so scared showed him Vasya also cares for him as a person. And that was exactly what Vasya did also just a moment before, when he thought, "so, Yoon can get angry too". He was finally seeing Yoon as a person.

Yea you can call it development but I don’t think their relationship is messed up whatsoever yoon might not have a legitimate Feelings for vasya and even though yoon would do anything to get away from him I think they just need some time to get to know each because the didn’t start of the right way in any way possible
Awww poor Euijoon feeling bad about Ajusshi possibly sleeping with someone else :(( Don't worry bb, he's only yours!!
