Mandy Wong
Vincent is a well-established designer and CEO of his own company because of the backing of his mother. When he assigns Kwai Yi Hei (Yi Long San's cousin, played by Mandy Wong) to renovate one of his open office areas, he is disgusted by her smell and tomboyish looks, but things that later change when he falls in love with her abilities. Kwai Yi Hei is also a talented spray paint artist and Vincent unknowingly falls in love with the Banksy-style HK art that she did while he searches for meaningful art. Only after learning the truth that Kwai Yi Hei is the actual artist does he begin to develop strong feelings for her and begin using strong-arm tactics to extend the length of the renovation project in order to spend more time with her. After a series of fights with Vincent, So Kei quietly explains to Kwai Yi Hei that Vincent cares about her and that he has risked his health (as he is a sensitive asthmatic) and career for the sake of her. Eventually, the two finally recognize each other's feelings and begin secretly seeing each other, but not without the ire of Vincent's mother.
