In one episode, the winning man asked Jin Lu how many girlfriends he had talked about. Jin Lu frankly admitted that he talked about several girlfriends, but he didn't really want to marry home. Of course, this is due to the influence of Jin Lu's female assistant Riemann. In the play, Jin Lu broke up with his ex-girlfriend because he cared that Jin Lu always had no news at work, but he didn't have much time to spend 24 hours with Riemann, while Jin Lu faced his ex-wife, which seemed unreasonable to him, in front of Li Man. In fact, he may have lost his feelings for his ex for a long time, but it is extremely irresponsible to dump his girlfriend on the pretext of Riemann.
Since I have no feelings for my ex-girlfriend, why not just say goodbye, but in front of another woman, or the object of my girlfriend's suspicion? Since he doesn't love, why should he just say goodbye? This is love rat, irresponsible. However, he didn't do this to Gu Shengnan, and made it clear that he and Riemann are just partners and good friends, and they will always defend the winner in front of Riemann. Perhaps this is the contrast technique adopted by the director to express the significance of winning men to Jin Lu.
