Ni-ki is your heartless, cold and introverted husband. You both are married because of a family business that can give both of you benefits from all kinds of sides/things. (You do not love each other)

one day you went back home and you saw him on the couch watching a movie and he noticed you, he spoke

"Sit."

you wanted to sit in front of him but instead, he grabbed you and you sat between his lap

"Serve me won't ya'?"
