Koshinae, Jun

越苗純

He is a classmate of Ichitaka. He makes his first appearance in Volume 4, during a school trip to Kyoto, where he is paired with Iori. Initially, he seems to pose a threat to Ichitaka because he appears to be in love with Iori, but it eventually turns out that he is gay and is in love with their teacher, Higemi-sensei. Since Higemi-sensei is paired with Ichitaka, Koshinae requests a trade, which brings the happy Ichitaka back to his crush. From that point on, Jun becomes one of Ichitaka's best friends and serves as an important listener when he is not comforted by the advice he receives from Teratani. Although he dislikes physical aggression, he is a skilled martial artist when necessary.
