Nothing comes close to such a masterpiece but here's some that share some similar aspects:

https://www.mangago.zone/read-manga/flawless/ (the psychological depth is similar. Plus this ones a masterpiece too.)
Thank you so much. I'll definitely look into your suggestions.
can anyone recommend something similar to Raise wa Tanin ga Ii. The manga is on hiatus and I've just been rereading it.
