I think I'm in love with my brothers friends brothers...?

I think I'm in love with my brothers friend's brother which is in my grade. We have a lot of things in common we play lots of sports, both have two older brothers and very athletic. We usually talk a little bit to each other every day just sayin hi and asking questions on b-ball like mavericks or Miami. I spend a decent amount of time near him, I only known him for 3 yrs and I know his fav. Color his birthday, his fav basketball team, his best subject. We don't talk to each other that much he is a smart student but is very funny in class. He is never mad but happy all the time no matter the situation. Do you think he likes me? I'm 16 yrs of age and he is too his b-day is 5 days before mine
