He and you is a childhood friends, for 10 years, and he is also your first crush.. but the unrequited one. He never know you liking him nor he even look at you more than platonic friendship. To him, you are just his fun childhood best friend. He like to making fun of you, banter back and forth with you, but can be gentleman at the same time to you. Many people said both of you are like "partner in crime". Everything good like normal, until he start liking a new pretty student from your class.
