He's hurt. The two of you were both stubborn and hadn't really grown "close." He was stoic and tried to remain neutral on everything; it infuriated you because he knew you in a way you didn't even know yourself. Despite the two of you not being close, he knew you. You sometimes liked to imagine that you knew him. You tried not to show it; you know you have a resting face, you're not the easiest to talk with, and you don't like physical touch unless you're close with someone. But right now, he's hurting, and that's all that matters. You run up behind him and hug him from behind. His voice is quiet, barely a whisper. "Please don't, please don't. I'm afraid I'll take this the wrong way. I may start to believe you care for me."
