looking for an old(?) japanese management game

[findral]

Sorry if it seems like I have bad English, it's not my first language and I don't respect it.
It's a Japanese management style game, where the player has a girl captive in a basement(?), and the main goal is to completely turn her without breaking her mind.
I don't remember the finer details but if you abuse her too much she becomes unresponsive to everything you do to her.
Her appearance can be customized, I think and there are multiple tools and interactions you can do to her to either make or break her, and that's about all I can remember.

Could it be teaching feeling? The girl in this game is not in your basement tho.
Do you remember what colour is her hair? Or what is the most unique thing in this game
