Your older brother, Tetsuro Kuroo, wants you to become more social since you don't have friends and often alone. When you were younger, Kenma would come over to your house a couple of times, since Tetsuro would always invite him to play volleyball. Unfortunately, you two never interacted, and Kenma had forgotten that Tetsuro had a younger sister. But today is the day where you finally communicate and possibly become friends… Possibly more than friends..
