I don't think Cain even knows Jooin has lingering feelings because even Jooin is sure he doesn't have them. Jooin had already told Yahwi no and to keep distance while he told Cain he wants to get to know him better before giving an answer. I think you're confusing some aspects. Even in the the recent chapter Jooin wanted to leave and was annoyed by Yahwi he only went because Phil asked him too
i think he is using cain to move on from yahwi :/
Got disagree with you there. I don't see it because Jooin hasn't been actively looking for Cain, Cain just happens to be there. Cain was the one who inticated their moments not Jooin. Rather than saying Jooin is using Cain to get over Yahwi, it's more of Cain helping Jooin get over him
yea anyone can interpreted as they want as it is from each one of us pov .
I feel bad for cain but like he knows jooin still has lingering feelings for yawhi and the dude still hangs around waiting his turn. Jooin needed to really tell cain NO because it's unfair to keep you waiting. They're all kinda terrible people but they're relatable because irl people are terrible too. If jooin realized hey maybe I'm in love with both of em this story could finally go somewhere lol
