As someone on tw said, Yahwi is basically doing what Cain is doing for his love of Jooin but the KEY difference is Yahwi is not taking in Jooin consideration or feelings and being forceful, while Cain knows his limits and unlike that rat clown, Cain apologizes whenever Jooin gets upset. BUT I do think it's ridiculous that the only reason Jooin is upset with Cain is because Cain isn't telling him things. While his anger with Yahwi is so many things, like being humiliated by him, being lied to, mistreated by him because Jooin didn't remember and also SA by him but Jooin is considering the two on the same level when they aren't.
