It will probably turn out well. This isn't a melodramatic manhwa. They'll talk it out, Fanboy will probably apologize for keeping things a secret, mom will apologize for not being more supportive, and she will probably be supportive of Fanboy after that.
I mean, look at how this manhwa handled the girl that had a crush on Fanboy. The author didn't really make her into a monster seeking to destroy the happiness of our babies. She just let it go, and the story moved on.
Yeah, that's why I'm not as worried tbh but I'm still looking forward to see the conversation happen between them because it's really necessary for Fanboy's growth! Hope mama becomes a super supportive one, that even in the near future Fanboy is able to introduce Star to her... even as a friend would be fine.
Fanboy mama already suspects Fanboy is doing acting behind her back, that's just how moms are they know everything. Fanboy already did a whole web drama, and as much as that can be hidden from his mom (since moms aren't really as fond of the internet as teenagers or such) once he gets cast for a regular drama (or appears on a regular show maybe) there'll be no turning back. I just want to know why is his mom so against him acting? Maybe because it's an unstable job? I just want him to be happy and feel supported by his family, so I hope we get that soon and it has a peaceful ending too!
