[Knittel]

I am trying to find a game i played long ago, was about a guy who goes to art school with some girls, there's a dating app on the phone, one of the girls has black hair and blue eyes, she's the best friend of a redhead girl that likes the MC, there's a husband to the "teacher" who cheats on her, the theacher changes clothes in front of the MC, there's other girls, an emo one, they like go to a house in the middle of nowhere as students. Never did find that game again, can someone pls help?
