Yahwi will deal with his issues and confess to Jooin and about Cain, he's either gonna do something weird/bad (or maybe he's already done somthing) or Jooin just won't fall for him. It's pretty clear Cain is a supporting character in my opinion and will only serve as a plot device to get Yahwi and Jooin back together. I am not saying that Yahwi is a saint I am just giving my predictions ( ̄∇ ̄")
