Sumika Murasame's friend, Ushio Kazama, reveals that she has a crush on a second-year girl from the school library, Chizuka Nishikigi. Sumika warns Ushio that Chizuka may have someone else she likes and that Ushio would just get crushed, which makes Ushio unhappy. The next day, Sumika saves Masaki Akemiya from a falling box, though she denies that she is a nice person. Later that day, Chizuka turns against Ushio because the guy she liked had taken an interest in Ushio instead. Sumika, who had waited to apologize to Ushio, then arrives to comfort her and later makes up with her. (Source: Wikipedia)
