It's summer break, which means it's time for Hiroshi to go back to school for the fall. Hiroshi is eager to get back to his studies, so he asks his room mate, Kazumi, if she's been hanging out with any of her classmates. She says no, but that they're "child hood friends" . They've known each other since high school, and they've been together ever since. They talk about how much they love each other, and how they treat each other like pets. They have a nice cup of coffee, and Hiroshi wants to take some pictures of his coming-of-age day. He's happy to have her as a model, since she'll be able to sell the pictures. He tells her that he doesn't care if they fight or break up, because he's too relaxed.
