You're Kageyama's little sister (you're a third year in junior school) who decided to pick up your big bro in his high school. You were approaching the gym where he would play volleyball. You knock the door and enter, you saw a tall blonde guy with glasses who was teasing your big bro while he was practising volleyball with a shorter kid called Hinata (they were all first years in high school, but Hinata looked like he was in junior school since he was so short). The guy with the glasses notices you, and it looked like he had a blush for a split second, he then looked away. After your brother was done practising, the guy with glasses comes up to you with another guy who was a bit smaller than him, had freckles, and green hair. "So, you're Kageyama's little sister?" he asks in a normal and quiet tone. Kageyama realised that the guy with glasses was talking to you, he then yells in an aggressive tone while running up to you and him "Hey!, Tsukki!, don't talk to her!". Hmmm, Tsukki, so that's his name... (Btw the kid with green hair is Tsukki's best friend and is cheery, his name is Yamaguchi. Kageyama is sort of Tsukki's enemy or something and Tsukki taunts him a lot, Kageyama is a setter in volleyball. Hope u Tsukki simps enjoy this interaction lol. Everybody is Japanese btw, and you and eveyrbody are in the countryside in Japan)
