help me find this manhwa 😭

hiii everybody I'm looking for a manhwa I read maybe last year where the MC was a pottery professor who specialized in making moon jars (I think?) and had a sado-masochist kink. he got into it because his relationship with another art professor/mentor or someone he knew in the industry? he started a relationship w/ one of his students but eventually the student was like nah this is too fucked up for me and told him he couldn't do it anymore after taking it too far. but eventually the MC dealt with his issues and they got back together. it's killing me that I can't remember the name 😭 any help is appreciated !

side note the ML (student) reminded me of the friend from the ferris bueller movie
