Hidden cameras reveal what really happens between a man who only wants to fuck and a sheltered 23-year-old woman named Minami. It is her first time visiting a man’s home, and their Christmas party begins with a teasing penalty game that she wins three times. She lets the begging man touch her upper arm, then playfully shuts him down when he gets carried away. Curled up defensively, she blushes when he asks for a kiss and tries to evade him, but their eyes meet. The untouchable beauty who normally refuses every offer gradually gives in to the Christmas mood and ends up having sex with him.
