I'm pretty sure it's Sooin's traumatized thoughts that came up a happy one and a very upsetting one. I don't think we have to worry as I think Hwan will be very happy and pleased with the rings although I do think he'll be waiting all worried cause Sooin went out while he was asleep.
Everyone's saying Jooin should be with Cain or Jooin should be with Yahwi but what if Cain and Yahwi get together? LMAO IMAGINE AHHAAHAH that'd be weird. I think Jooin has to realize and pick what's best for him. Maybe he won't pick any of them and that's fine because he needs his own happiness and look at the mess he's in right now. 2 guys confessed to him and it's making his head spin.
As the readers we should respect the decision. And sure we all have our personal taste and are hoping for Jooin to be together with either Cain or Yahwi but in the end I'm just hoping everyone will be happy.
