Is it normal that I really care about my best friend?

hey everyone I know you think it sounds stupid but I jus wanna find out if hou have a bff and you care a lot bout him. Me I really care about my best friend and like I would do everything for him and don't get mad at him even if he makes me. It's like he has every very important place in ky heart for me. soo what do u think? tell honestly do u have the same feelings?
