ForManaga
If this is the actual story behind her and mc in the other story i dont even blame her for cheating. Obviously she should've broken things off before going for another guy, but the mc just kept ignoring her and brushing of the idea of getting a job after her telling him multiple times. Relationships are all about comunication and once thats off the table it becomes unstable.
ForManaga:Yeah, Although in the novel they don't go any details and being he was the protagonist of novel it's not mentioned much but from the little details in story, you can guess it.
