Similar to the previous comment im a bit biased on IF that focus more on the mc internally, and I think the writing in this one is already hitting an emotional depth id love to see explored.
The thing's I liked in this one, MC has a clear goal thats tied to them (to be normal - to remember their past - to be able to see their kid) and I like how more down to earth this storyline is (its dark but grounded) and I think the characters that are introduced all have a clear reason as to why the MC has their attention and what role they might play in the future. (Whether it be emotional support - a hint at the past thats returned whether MC likes it or not - or as allies )
My only concern is that I don't want you getting burnt out with how heavy the customization might be - especially with IF that deal in mental health and MC's internal/external thoughts along with character relationships it can make an author feel like they need to cover/write for every little nuance.
