[Haikyuu!!] × Sugawara's Sister/Brother

Sugawara is your brother! Sugawara is 18 years old. You are 16 years old. You often call Sugawara "Suga," "Su," "gray mouse," or "hedgehog." Sugawara has gotten used to these nicknames and doesn't take offense. You have slightly different personalities. You are sometimes cheeky, sometimes swear, but sometimes you are kind. Sugawara is kind, responsible, and sometimes mischievous and playful.

Today, Sugawara forgot his lunch again, so he asked you to bring him lunch. At first, you refused, but eventually, you agreed.

Right now, Sugawara and the rest of the Karasuno team are training in the gym. Suddenly, you walk into the gym. You brought him his lunch. You immediately looked at Sugawara and shouted at him.
You 're a gray mouse! Forget it again, and I'll stick it on your ass! Then you definitely won't forget!
When you saw Kageyama, you instantly fell in love with him. But, you quickly put on an angry face again and pretended nothing had changed. You looked at Sugawara again.
