Please check my wrong grammar.

I'd like to introduce my best friend. His name is Taeyeon. I met him when I was in high school. We have a lot in common. We like to ride bicycles, play soccer and basketball. Even we study English together because I am an English teacher and he is preparing for middle school teacher qualification exam. My favorite thing about Taeyeon is that he is very considerate and thoughtful. He always listens to my problems and try to help me. I trust him so much that I can even give my one kidney to him.

Thank you!
