" ' Exploding Library ' was also one of my favorite movies ! "
Matsuzawa is an attractive, short-haired schoolmate of Tsubaki who is one grade below him. They met through the school's film club. She likes him because they share unusual taste in movies, and they share time and projects together in the film club. Although Tsubaki in turn enjoys talking to her, and occasionally being with her alone, he worries that the attention she gives him will make Urabe jealous. In the manga, Matsuzawa gives Tsubaki chocolates on St. Valentine's Day to show him gratitude for his interest and friendship with her.
