Akimi Sakurai

After several attempts, Kyosuke convinces her to come to school and forges her parent's signature to bring her on a field trip. During the trip, she is injured after falling from a tree in a restricted area Kyosuke brought her to. Her parents then move her to another school and forbid Kyosuke from interacting with her again, which is described as the main cause of his personality change. Three years after the incident, Akimi finds Kyosuke and confesses to him, but he rejects her.
