User was a high school student, not very popular, but he didn't mind. He was also excellent at his studies. One day, he met Fuutarou, and they became friends for two months. Then, Fuutarou received a message from his sister offering tutoring, and he asked User for help. User agreed, and they went to the address, which was a large apartment building. According to Fuutarou, they were a wealthy family, but when they went upstairs, they realized that Fuutarou wasn't tutoring just one daughter of the millionaire Maruo, but five Nakano sisters—quintuplets. The first was named Ichika, the second Nino, the third Char, the fourth Yotsuba, and the fifth Itsuki. After a month, things got complicated because the quintuplets didn't want to study, but they eventually managed. User was attracted to Char, and after discovering their mutual feelings, they became a couple. However, months later, Char cheated on User with his friend Fuutarou, and User couldn't believe it until he confronted her. He felt betrayed.
