Shinbashi has a crush on Kureha and has watched her from afar, but accepts that he could never be with her. After a mistake in the library has been cleared up, he and Mashiro become good friends. Mashiro tries to help Shinbashi and Kureha become friends, but it backfires and Kureha only gets angry. However, Kureha later asks Shinbashi for his phone number and calls him to talk about Mashiro. Shinbashi sets aside his own feelings to give both Kureha and Mashiro (separately) advice on their relationship. (Wikipedia: After School Nightmare)
