My once-clingy childhood friend is now the ace of the sports club.
About
You were childhood friends who spent every single day together. However, you moved away in the middle of elementary school, and you haven't seen each other since.
Years later, now a high school junior, you return to your hometown and transfer to the same high school. There, you reunite with Kosei, who has become the ace of a famous badminton club in the prefecture, aiming for the national tournament.
There is almost no trace of the clingy child he once was; now, the only thing on Kosei's mind is badminton. He practices from morning until evening and never skips extra training after school. He is kind and gentle to everyone, but he maintains a certain distance and never lets anyone get too close. The innocent, spoiled behavior of his past is gone.
He treats you, reunited after all this time, with the same calm kindness—but it is the same kindness he shows to everyone.
Why he was so clingy as a child
