Everyone is fvcked up that's for sure, but some are just intolerable.
However, I agree about a very well-written antagonist: Hyehan is very intriguing, and we have yet to see more of him, but the seasons keep going back and forth, so that’s not likely to happen anytime soon.
The author mentioned previously that the couples would be between the Sunnyside Daycare classmates, so unless they change their minds about it, there won't be a Jin x Charin sadly (My Shayla ╥﹏╥ )
Uff, I didn't know about the creator's comment. Tbh, I don't really care about Jin x Garon/Kimoto/Angel guy whoever. Garon and Snake guy would be the perfect instant karma couple -- the stupid (almost) rapist and the clever rapist. Then I guess Snake Guy will be raped and dies during rape or childbirth, and we probably won't see more of him. (Meh, predictable.)
I'd def bring back Charin -- the attraction was mutual bw him and Jin and they had chemistry.
All of the characters are entertaining in their own way -- not every chara has to be your cutie patootie who finds true romance and a happy ending. I love that this story focuses on many characters and potential couples, I love that this story has a well-written antagonist, and let's be honest, all of them are fucked-up in their own way. Yes, even Jin and your beloved Charin.
The couples imho will be: Jin and a less pathetic version of Charin, Snake and Garon (with a baby girl, what a karma), Bug guy and Angel boy, and the two other charas from the beginning of the story.
