From what I remember it was about a two students, a male who’s like a strict person that already known in that school and a female who’s a cheerful person. All I remember was the ending, both painted either the roof or the wall of the dormitory. Then few years later, their daughter attended that highschool. They were known as famous couple in that school. Also the female have a pet bird. Please please help me I don’t remember the name of it!!!!
