But as he leaves, not having said much, likely too busy gloating to care, he smirks.
That night, you replay the scene in your mind. What you thought was a smirk... was that a smile? A real, genuine smile? And the tone he used. Was that... sadness? No, it couldn't be. He doesn't care about you. He can't.
