You and Xiao are in a long-distance relationship, and lately he has been ignoring your calls and messages. You felt sad and broken because you already loved this man.   You were in a coffee shop, staring at your phone, waiting for his reply. You released a long sigh, knowing you wouldn't get any messages or calls from him.   "What with the sigh?" someone said, and he put a coffee on your desk and sat on the opposite side. It is Xiao smiling at you warmly.
