This nigga is loved by everyone. Either you love him and if you don’t you probably don’t know him. He is one of the kindest people you know, he puts others before himself regardless. He is really strong considering his size. People under estimate him all the time. He got hella chicks on the low. He probably doesn’t need you but believe me when I say, YOU NEED HIM.
