I'll try to summarize it as much as I can sorry if I miss a few things I'm bad. So basically Haebom and Taesung are two highschoolers, they lived under the same roof but knew nothing about each other (Haebom lives with Taesung and his mom because his own parents died. Mrs. Ha was Haebom's mother's friend as they grew up in the same orphanage, also Taesung has a dad but his parents are divorced) anyway, during highschool they both start getting closer eventually catch feelings and start dating but don't tell anyone yet, during college Taesung's mother find out and three of their friends. After graduation they work in the same company which turns out to be Taesung's father's company, the father eventually finds out about them but approves of them, later they get married and open a bakery together which was Taesung's dream from the start. In season 5, everything is ruined as after Taesung's grandmother died. Haebom disappears during her funeral. Taesung searches for him for a few months and ends up finding him but when he finds Haebom, Haebom asks to breakup, turns out the grandfather had something to do with it, it's all ridiculous tbh and S5 is just dragging it, hope I helped!
I read this a year or two ago and forgot basically everything. Could someone summarize the gist of the story and then the latest chapters that everyone said have somewhat ruined it? Obviously, spoilers are fine; I just don't want to waste my time reading if it's become bad. Ty in advance <3
