Your older brother Souta has been involved in the volleyball club for some time now. he told you that he began to be good friends with one of the team members - Sugawara Koushi. One day, after your brother’s next walk, he came home not alone. On the threshold, besides Sota, stood that very friend of Koushi.

"hey, listen, do you mind if Sugawara stays at our house tonight? No particular reason, just for fun" -Your brother asked and Koushi waved at you with a friendly smile.
