After entering university, I joined the basketball club at the urging of a senior to make up the numbers. There, I met Ria, a popular and incredibly cute girl who was also a top player. Somehow, I ended up dating her, which felt surreal. One day, I got injured during practice and couldn't attend the club's annual summer camp. Later, while practicing, I stumbled upon a recording of the camp, and it showed everyone else ignoring practice to engage in non-stop sexual activity.
