Writing Feedback / The two friends I can count on - help with grammar! [5]

I've had a lot of friends but these two friends are the only one I can count on and will always be there for me. This first friend is a guy I have known since grade 7; He was a transferred student who recently moved in the island. On his first day of school he came up to me and said "wanna be my friend?" I laughed, hearing someone still says that in this age and I thought it was nice even though it was kind of straightforward. We got to know each other and found out we shared similar interest and opinions. I knew ever since the first time we met that were going to be close. Thereafter, we started hanging out and doing crazy stuffs and there was a time when he came to sleep over at my place where we spent all night playing video games cautiously so we don't get caught by my parents. He's fun to hang out with and will always have your back every time even now. This second friend is a girl I have known for about two years. She is the exact opposite of my first friend. She is more serious and don't talk to very much because she is shy although I would tease her and she would smile and laugh and would start talking to me. She is a good listener, who is there for me whenever I need to share my thoughts and would understand me when others can't seems to understand what's wrong. My first friend and she are both someone who I can just sit and talk to for hours about stuff that really doesn't matter and would not get bored. They're also the people that I can trust and really admire as a person.
