She entered her designs in a competition in hopes to make her name more known and also to get the chance to meet Paul Lee, a designer she admires greatly. However, when she meets him after winning 1st place, she realizes that they’ve already met before but due to a previous unsavory encounter, she starts to dislike him and hopes to not see him ever again. During her birthday party, Kat is given a Jade necklace from her dad and told to be an item that belongs to her mother. Unknowingly, that Jade necklace belongs to her biological mother, HuiSan, who’s going to die from cancer soon. As her dying wish to see Kat one last time, Kat decides to go visit her. After HuiSan dies, Kat is told to stay in Hong Kong to take over the family business as HuiSan's heir. Kat is hesitant because her family in Thailand is anticipating her return.
