A villainess trope, but a trap. Kind of. I feel like it seems like it's starting somewhat "wholesome" with the premise of the man having fatherly feelings, but the opening suggests yuri, so... I guess at some point he will decide to pursue the "heroine", because why not do it since, it's not real world? Even if not, I feel like it probably will become old as the MC to watch how he tries to be villainous, but being just stern and "composed", which simply makes him look more noble and "appropriate". At least I did not notice here anything else, that could keep my attention.
