I hope in the end of the story Cain doesn't start doing some dumb shit to Jooin and then Jooin goes back to Yahwi. Not only would this make Cain's actions not line up (like calling him master and being nice), but it would make Yahwi's manipulation work and Jooin a 1 dimensional character. I know this author isn't the best with plots, but they could make it good or make it dull like their other stories.

Ikr, if the author comes up with some shit that Cain is a bad guy or something, it’s not gonna match at all with his actions till now, it will only look like a forced attempt to make Yahwi look like a better person and have him act heroic, just for Jooin to forgive all the crap he did to him at the end... uhm yeah, that’s not gonna work, it would ruin the whole story. If it happens I’m seriously dropping this.

I don’t know Korean by the way:
Cain puts Yahwi to sleep after taking care of him and notices him crying while asleep. Cain gets the feeling that Yahwi’s the one who is making him cry. The next day, Yahwi is smoking with his friend and catches Jooin talking with Cain across the street. Yahwi walks toward them and says that they should all have a “double date” (friendly) meet up and they are talking over booze. Yahwi’s friend and Jooin excuse themselves to go to the bathroom I think and while they are away, Cain and Yahwi talk with hostility toward one another (Cain is speaking fluent Korean). Jooin comes back and hears Cain speaking fluently and feels tricked. Yahwi tries to take the opportunity to get with Jooin and is rejected. Jooin ignores both of them and makes his way home, while Cain is trying to talk it over with him as he walks home. They talk for a while inside Jooin’s house and Jooin eventually forgives Cain. Afterword, there is a lot of romantic tension in the room.
This is so cute
