He has a nickname, Mr. Cool (played by Donnie Yen). In fact, he also wants to laugh, but unfortunately he really can't laugh. Laughing only brings him severe pain. "Where is Ah Tang?" The girl Qiao (played by Michelle Chen) has been looking for him, "Who are you?" She has been asking. Only she has seen his smile, but unfortunately she is like an external memory card with only 50M memory, and she will forget it at any time. Ah Zai (played by Ko Chen-tung) is the youngest policeman in the eavesdropping team. He can hear the heartbeats of many people in this city every day, but the only thing that accompanies him is pork chop rice. On the day of eating curry pork chop rice, he met Shengnan (played by Angelababy) wearing PRADA. On the day of eating Japanese pork chop rice, he and her played a game of only playing romance but not love. 7 days later, he heard her voice in the bug. The three most romantic words in love are not I love you, but together. Can they be together?
