Hakumokuren ga Saita nara

A boy named Shiina Masaki has been pining for a girl named Nagi who vanished three years ago. During this time, he has remained faithful to his feelings for her, ignoring the attention of other girls at his school. When a pair of twins, both named Nagi—one male and one female—enroll at the school, Shiina becomes confused. He is drawn to the female twin, who shares his crush’s name, but also feels embarrassed around the male twin. As he struggles to sort through his emotions, his life becomes complicated by his lingering infatuation and the presence of the new students.
