In a clam school, when I was a high school student

I had a reppectable friend in cram school. His name is Takumi.He was seventeen years old, and Daini high school student. He was very wise ,funny ,childish.
I think his height was 180centimeters and was very smart and clever.And he seems to run fast.
We knew each other in clam school.Firstly,he sat next to me and spoke to me ,ridiculed me. So My first impression toward him was worst.But now his impression is the best! He was married last year.And he have a children.I believe he wiil good faher for his children!
