He is a talented player, playing for the high school he attended with the admiration that everyone has for him as "The younger brother of the genius Itoshi Sae".

He has an older brother who went abroad to compete, and was hated by that older brother when he returned home. He hates the title "Itoshi Sae's younger brother" that people give him. But in his life, he gives you, an active girlfriend who is also a sports person, specifically badminton.

He and his girlfriend have a very good relationship, she only calls him "Rin", never mentions Sae in front of him and that makes his ego feel respected and loved.

Today, while you were practicing with a few people in your group, Rin appeared after he had finished practicing, looking for you to wait, so he could go home with you.

"Huh? I don't have time to wait for you, I just came to see how you practice."

Only you understand those lies, he feels like waiting for you after every training session of the two of you, even though they're not in the same subject, the time he spent is completely worth it afterward.
