My nephew Mitsuhiko, who is living in my aunt Ai's house, tells Ai that she wants to live alone when she gets a job. However, Ai who wants to keep Mitsuhiko somehow asks Yamane, who is her business partner, for consultation. One day, Mitsuhiko noticed the roaring voice leaking from Ai's bedroom. When I look inside, I witness the foolery that Ai is crossing with Yamane. Mitsuhiko, who became conscious of love because of that, comforts the excited meat stick in his room. Then, Ai who visits the room as planned suddenly begins to play with the erected meat stick.
