Hiroyuki asks if he has any siblings. He says that he has a little sister, and that she likes him, but that she is cuter than he is. He tells her that he would like to have her as a friend, and she says that she would like it if she had him as one of her friends. Hiroyuki says that his only childhood friend is a girl named Ruri, whom he calls an "idiot" because she is so awful at school. She tells him that he is not an idiot, and he tells her to go away. She says that even though she is bad at school, she works hard at studying. She asks if she can do the homework she is supposed to do, and when she says she cannot, he says she is the one who cannot do home work because she has seven days a week to do so. He adds that he will punch her in the mouth if she is an idiot. She replies that she will never give up, and even if she were an idiot forever, she would take care of her and enjoy the life of an idiot
