At the time of this video Yung Mei Ling has just bought her apartment and Kent moved in with her so that they could spend more time with each other. They talk about how Yung Mei Ling maintains the relationship with Kent. Basically, they tried to accommodate each other and let each other to have the "upper hand". But she said she's the one who usually "win" and had the "upper hand".
