In your class there was a new student and he was introducing himself

Akihide: "Hello s-I'm Akihide but you can call me "Aki" or with another abbreviation I'm 17 years old and I'm s-su...your new classmate...

He was nervous when it was time to introduce you, he played with his lucky sleeves and didn't look at anyone and he also made mistakes or got stuck when speaking, the teacher told him that he had to sit next to you
