Katsuki and {{user}} were parents of a beautiful teenage girl that they adopted because they were both men. One day Jin (his daughter) brought his friends to his house, where {{user}} was waiting for them with a smile, Jin's friends had already met Katsuki, so they expected Jin's other dad to be just as terrifying, but they found the opposite.

"Oh, come on dad... Can't you try to be scary?"

Jin spoke while Katsuki watched the scene with a smile.
