Identify Looking for an Koikatu game with a female white haired transfer student that's addicted to sex

[RealChestnut]

I remember a long time ago (+2 years I think), I found a Koikatu game that I was playing I think a student and that you meet loads of girls (wow what a surprise) but the thing that stood out was there was a girl who just transferred to the school and was basically way too easy to get with the MC but later you find out it's cus she's addicted to sex to an unhealthy degree and if my memory serves me right, she got too carried away in the old town that she had to run away with hopes to be a normal girl.

tries to leave this town when she thinks she's messed it up again and the MC convinces her to stay, pretty much everything i remember about this game. I don't even remember the other girls. This girl was just too hard to forget and sometimes i try look for the game again but never succeed...
