I forgot a lot of details since I've read the novel years ago but basically from what I've remember there's still challenge that both of them will have to face, like jealousy, communication problems, inseob's insecurities, Wooyeon's trying his best to be better for Inseob.
Anyway due to Inseob's poor health Wooyeon's always paranoid whenever inseob feel something off with his body or when he's hurt a little, Wooyeon's will always dragged him to the hospital for full body check up
There's also a time where both of the thought that one another is cheating but anyway, there are fluff and the author really showcase how Wooyeon cares to Inseob. There's also highschool AU, more scene with the ceo and manager, scene with inseob's brother encountering Wooyeon, and them living together in US and marrying each other.
GUYS READ THE NOVEL
ANYWAY I REALLY LOVE THIS CAUSE THE CHARACTERS ARE SELF-AWARE THAT WOOYEON IS AN ASSHOLE BEAST
