I have a feeling...hear me out... Cain is using Jooin to try to make Yahwi jealous. I think he knows Yahwi (maybe they’re families have beef) and he wants to make him mad and kinda like idk fuck him over??? Just a theory
It can be possible because they r cat & dog
But he knows Jooin the first time he saw him? And even called him Master and If I recall Yahwi and Jooin doesn't have relationship at that time
