They’re all shit characters really but I think jooin is the least in the wrong. Unless Ive forgotten or missed stuff Jooin split up with Yahwi and was upfront about rejecting him but Yahwi continues to stalk him and push him into kissing him so I wouldn’t say he’s leading him on. Cain on the other hand won’t tell him ANYTHING about his life. I don’t see how you could trust or date someone who won’t even tell you the reason why they’ve had to go back home to another country and won’t give you any information about their life. I most certainly wouldn’t date someone like that he deserves getting shouted at a little bit.
If Jooin keeps this up - especially with the whole yelling at Cain, taking his frustrations out on him, while simultaneously leading him and Yahwi on - then screw it I'm going to start rooting for Cahwi. Cain would probably be a way better boyfriend for Yahwi anyways, and not Jooin who's seemingly clueless and cant make up his mind 80% of the time. Like is it really that difficult to choose between the two of them????? But no he's dragging his feet, leading them both on like he's got all of the time in the world.
