Looks like I'm the only one on joins side huh..

Jooin is unfair to Cain but only because he didn't want their relationship to be simular to his and yawhi (I think I spelt his name right) before going into this relationship he wants to know what's going on with the other person before it gets problematic into the relationship. if Cain is truly serious wanting a long term relationship with jooin he'd tell jooin what's going on. I'm sorry But this needs to be said. you can't keep secrets that can affect the relationship and expect everything to go well its unrealistic but what is realist is telling the person everything and working through it together, that's what builds a stronger relationship and that's what jooin wants, all he wants is a relationship where both parties are putting in the work together no secrets between each other as well
