Don't know man, but i think that kangjin and jungwon shouldn't be going back together, because of first love or sth. Rather, i think the story will be very exciting if they are still the main character, but not being a couple, showing how they solve problems and move on each of their own way, and just be friends. Sure they misunderstood the past, but if highschool love still strong after 10 years not meeting each other, its more like sympathy and guilty of the past and not love anymore... And i love daddy chisoo uwu, so please don't make daddy the bad guy 0-0
