MC is a traveler through stories. He is to make his villain love him. I cannot remember much.

MC was arranged on a blind date by his family to a Cat demon Earl. MC valued good looks, and he immediately fell in love. Not only that, but the big cat also found it hard to resist. (Animals become humans)

MC "tricks" his now demonic father into believing he is his child. He leaves for adventure only to find out he has been cloned multiple times and to not disobey his father.
