It's summer break, which means that it's time for everyone to go on vacation. One of the girls, Asamitchi, is worried about what's going to happen to her boyfriend, Takeshi, when he's gone on vacation with another girl. She's worried about him, too, because she's heard that Takeshi's been hanging out with a girl who's also going on a trip with another guy. She wants to make sure that he knows about it, so she goes to him and tells him that she ran into him on the street, and that she'd like to talk to him about it. Takeshi agrees to go with her, but he doesn't know how to handle it. Asamutchi is upset that he hasn't been able to get her boyfriend on his side, and she tells him to be careful. She also tells him not to get too close to Takeshi because she knows that he won't be able to catch him cheating on her. Asamitachi, however, isn't so sure, and he tells her that he'll try to take care of the situation himself.
