Hana, his mother's friend who came to Tokyo to help her children move, comes to stay the night, and Yasuo, his son, can't contain his excitement. As the night draws on, things get more lively, but his mother kicks him out, saying "now it's adult time," and Yasuo is left alone to fret. Then Hana, drunk and in a good mood, comes into his room. As he listens to her story, Hana gets closer to him, making Yasuo's groin swell with tension. Noticing this, Hana smiles and kisses him. Then she leaves the room, saying, "We'll continue after Mommy goes to bed."
