yeah - Mom discovering Waka's existence will likely go one of two ways, that I can see.
- Either she'll understand that he's a source of strength, encouragement, and motivation for her daughter--and she'll remain "hands off" and stay out of Minori & Waka's business--provided it stays relatively benign (as she sees it);
- Or, she'll decide that this constitutes risk of a "scandal", and force the two apart.
Of course, I actually don't know how Minori would respond in that second case. There's a chance she just tries to stoically carry on, despite the crushing blow that would be. Waka would try to respect it, especially if Minori herself breaks the news that she has to focus on her work and can't make time for him. He'd go along with that, certainly, and try to support her from afar, or something.
But I could also see Minori being headstrong enough to push back against her mom in this case. She's lost friends and connections before, sure, but I suspect Waka is different. This could be a case where Minori discovers her own limits and takes charge. Alternatively, she breaks under the pressure without Waka in her life, spirals, and causes problems right at the height of her budding career.
Which, if her mother is pushing all of this out of some need to live vicariously through Minori, could make her snap, blowing everything up all at once.
Depends on what the author wants to do--but the next few chapters will definitely set the tone for whether this gets super heavy, and what sort of character Mom will turn out to be.
Thanks for the TL.
