Atsushi heads to a friend's house to deliver something left behind by her father's remarriage partner, Ruri. When I try to press his intercom, I find a "out of order" sign on it. Since it was late at night, he couldn't raise his voice too loudly, so he tried calling, but no response came back from inside. When I had no choice but to put my hand on the doorknob, it was unlocked. When he timidly asks what's going on downstairs, he finds a man he doesn't even know is hugging him... Atsushi attacks to eliminate the betrayal of her father and the libido of nymphomania!
