Inheritance of the Tada Collection

Earlier, Tada had died and left Yūichi all of his pornographic magazines in his will. Rika discovers this secret and becomes furious. Although Yūichi becomes remorseful and searches for opportunities to apologize to her, Rika only responds with pranks and resentful actions. After Rika locks Yūichi on the hospital roof, he falls ill and becomes a patient of Dr. Natsume, who had recently returned from a vacation. When Yūichi recovers, Akiko creates an opportunity for him to apologize. However, while waiting, he encounters Dr. Natsume and learns that he had been treating Rika for six years and only transferred to the hospital to keep watch of her. Dr. Natsume is surprised that Rika had told Yūichi about her illness since she had never done so in the past, nor had she ever made a friend. He gives Yūichi a pornographic magazine, and Rika catches him perusing through the magazine and again locks him outside; meanwhile, Akiko realizes that Dr. Natsume had purposely caused this because he found it "entertaining". Eventually, Rika and Yūichi get back on friendlier terms, but Yūichi becomes offended when Rika states that the only reason she wanted to apologize was because of Dr. Natsume's influence. In response, he harshly expresses his contempt of the doctor, and Rika throws her book at him. The book turns out to be both her father's and her prized possession, and lands on the top of a window.
