Hey just a couple of things:
At least from what I can tell there's no way to raise your mom's corruption to the level required for the shower scene.
Would recommend adding a corruption change when you are helping her. I would also increase the mood increase or decrease the threshold for the scene. It's pretty grindy. I added a $mcorr +3 to the living room, and bumped the mood increase to 5.
For the park scene, if you leave before exploring deeper, the scene won't trigger again. Either remove the leave scene, or don't set it true until the full scene has played out.
For Mia's scene working 25 times at the cafe seems like a lot to trigger that event. I would probably lower that threshold, or at least provide some dialog that indicates that the MC needs to keep going to work. Normally this wouldn't be a big deal, but without anything to spend money on it's unlikely for a player to grind that out without knowing that's what you need to do. I would probably just make it money threshold based instead MC Money above 1000 for example would be a good time to trigger it.
Cheers!
