I’m looking for a forbidden/secret relationship where the MMC is the son of FMC’s teacher

Hey everyone, I’m a sucker for the forbidden romance trope. Up until now I mainly read classical coach’s daughter novels but I am looking for kind of the opposite where the the MMC’s parent is the one important to the plot. I have looked but mainly stumbled upon student-teacher relationship which I am not a fan of. If anyone has any good rec I would really appreciate it 🙂
