Cover page: “Let me say, ojisan, can you teach me some things that a boy my age doesn’t know?” Inside Tatsuo’s house, Tatsuo says, “During the time, while Daisuke [太輔]..your parents are away, this place will be your home. Just treat this place as your own home so there’s no need for you to feel awkward here. *laying on the sofa, he looks up* ..by the way, Anna.” Anna brightly smiles and looks down on him. She replies, “What is it, Tatsuo-san?” Tatsuo nervously asks how come she is sitting on top of him. Anna happily says that she just wants to repay the favor of letting her stay there. “How do you wish me to repay you? At my house, I always help massage papa’s shoulders so my massage skills ought to be very good. Or maybe, it would be better to rub your back while you’re taking a bath? Ah..that’s right..even if it is only lately that I’ve learned it.. *leans down to his crotch* use my mouth..” Tatsuo blushes a bit and looks surprised. Anna smiles and lets out a laugh. “Geez--! Ojisan, you unexpectedly blushed- So cute- Even if you think about it, you ought to also know that it is impossible for it to be true!” This made Tatsuo angry that he shouts for her not to tease an adult. Narration: “That day, because of father’s willfulness, I’m staying in the house of an unknown ojisan.” At the school stairs, Anna is giving Takumi a blowjob. Takumi says that feels comfortable and did she also do this kind of thing to Tatsuo. She licks her thumb and says that she thought of it but in the end, she gave up. “He’s a very decent and complete boring person.” Narration: “Tatsuo-san is a SOHO [/work at home] guy so he always stay at home. Because they are old friends for 20 years, my father is also at ease with him. Due to all sorts of reasons, I’ve been entrusted to him.” While walking at the hallway, Anna thinks that it is obviously fine for her to live all by herself so how come she has to be with this unknown guy.. Since she is lost in thought, Takumi asks if she is listening to what he is saying. A male teacher calls out to the two and shouts that they’ve skipped class. While Takumi is struggling to say something, Anna apologizes to the teacher for she collapsed from stomach pain so Takumi only accompanied her, and it is because she has her menstrual period. The teacher backs away and just says that she should go to the clinic and get some medicine. Anna says okay. As the teacher leaves, Takumi says that she can really handle the teacher. Anna tells him that rhetoric is useless if it is a female teacher who bumped into them. “What I’m an expert in is..” Takumi asks what. Anna just smiles. Takumi asks what that means for she is smiling at him for no reason. Anna says that it is nothing. Narration: “To put it plainly, in this world, except for men, it is women. It is so simple that it makes one feel that it is quite a wonder.”
