A high school student named Sado Taro developed a masochistic tendency after being punched by a classmate in middle school. Now in high school, he wants to overcome this and live a normal life. He befriends Tatsukichi and learns about the Number Two Volunteer Club, which offers support to students in need. The club is led by Isurugi Mio, a strict and aggressive girl who often mistreats Taro, unintentionally triggering his masochistic reactions. Taro reluctantly seeks her help to address his issue, unaware that doing so will complicate his life further.
