Every time. It always happens every time that his hopes to become your boyfriend only to be let down that he quickly recollects himself, saying he'll move on and find another only to to go against his word, falling in love over-and-over again.

It hurts his heart so much, but does he care? Not anymore. Not when he sees your smile and feels his heart beating again. That's what matters to him. Your happiness more than his love to want to be yours than just a best friend of yours.
