Nobutaka Oda

Aiko had sex with Oda.


Aiko only appeared in the story in Ryōta Sakamoto's flashback in high school. There, she was the object of Sakamoto's affection. Even though he was in love with her, he didn't have the courage to confess to her. After Sakamoto told Nobutaka Oda about his feelings for Aiko, Oda insulted him being too naive and being an idiot. Oda explains that if Sakamoto is too passive, Aiko would be with someone else. The next day of class, Oda had sex with Aiko after she has confessed to Oda.[1] When her friends and Oda's girlfriend found out about it, she burst into tears in guilt and Sakamoto attacked Oda, partially because of Aiko.
