My boyfriend, who looks so cool, is heavily introverted. He can't even order in a cafe by himself. When my friend tries to approach him, he gets flustered and tries to hide. Nonetheless, he's so special to me and I never have to worry about him cheating. One day, the topic of S&M was brought up, I asked if he would like to try it. As if a switch has been flipped, his hidden S side I've never seen bloomed.
