Those are exactly the type of break ups that the person who was playing the leaving part, will regret that decision after years/decades, when they finally learn to appreciate the things (and people) that truly matter.. Like in this case, if Sumi were eventually blessed with a normal, working brains, she would realize some day, that she should put her own personal feelings first, no matter what the public-/fans opinion is..
If her manager would've really cared for her, she would've advised to do what feels right, since if she really has the talent for acting, she'll be successful regardless.. Now there would be a risk for her to grow resentful towards the manager (and the acting it self), for pressuring her to leave MC...
Anyhow I didn't really even like this ship, since it was really rushed and felt out of place.
ALSO, thanks for the chapter(s) and for the translation(s) 👍
