Misaki tries to convince Tatsuhiro to sign a contract with her, whereby he will be obligated to listen to her as she tries to ease him out of his hikikomori lifestyle. Later, Tatsuhiro discovers that his otaku neighbor is actually his high school friend Kaoru Yamazaki who is studying a media course in creating games. Using Kaoru’s book, he fibs to Misaki that he is actually a games creator, not a hikikomori, and that he could show her a game that he had made. Overhearing this conversation, Kaoru decides to help Tatsuhiro make an eroge, and assigns him the role of the scenario writer.
