Shuu Hagiwara

Occupation: Biology researcher

Shuu Hagiwara is a teacher and the ex-boyfriend of [Hina Tachibana](https://anilist.co/character/127595/Hina-Tachibana) due to fact that Shuu is married, therefore his relationship with [Hina](https://anilist.co/character/127595/Hina-Tachibana) for the last two years is an illicit affair and he also seems to have a good friendship with [Reiji Kiriya](https://anilist.co/character/135462/Reiji-Kiriya).

Shuu is a friendly and thoughtful person who has a playful side to him, owing to his puppets and ventriloquism skills. According to [Reiji Kiriya](https://anilist.co/character/135462/Reiji-Kiriya), Shuu was constantly sad and fatigued with having to deal with his wife. Because of his unhappy marriage, Shu was ready to take risks with his affair with [Hina Tachibana](https://anilist.co/character/127595/Hina-Tachibana). Unfortunately, he has been indecisive on ending the marriage for some time. When he noticed that [Natsuo Fujii](https://anilist.co/character/127594/Natsuo-Fujii) was in love with her as well, Shuu was a bit vexed, but nonetheless let [Hina](https://anilist.co/character/127595/Hina-Tachibana) choose between him or [Natsuo](https://anilist.co/character/127594/Natsuo-Fujii).
