Background / History

Jiang Yubai is sent by his mother to collect rent from a family-owned residential building. There, he encounters the financially struggling Lin twins and learns that his silent deskmate, Lin Tingwan, has an identical twin sister, Lin Jianxia. He agrees to delay their rent, initially asking Jianxia to explain the womanizer rumors surrounding him before teasing her with a proposal that she work as his maid. 1 2 3

Although Jianxia initially considers him a predatory rich young master, Jiang Yubai gradually becomes involved in the sisters’ circumstances. After thoughtlessly eating the meal Jianxia prepared for herself and Tingwan, he returns with groceries and lunch, then later uses his family’s authority as the property owner to make bookstore owner Zhao apologize to and compensate Jianxia. 17 19 20

After Jianxia loses her job, Jiang Yubai offers her paid work cleaning and cooking for him. He frames the arrangement as a practical solution to his own poor cooking and inconvenient suburban lifestyle rather than charity, offering her 1,200 yuan per month and staff meals for herself and Tingwan. 21

He moves from his family’s remote villa to an apartment in Splendid New Village, next door to the Lin sisters. He renovates and stocks the kitchen for Jianxia’s use, gives her a starting-work bonus, and entrusts her with a key to his home. 34 35 39

At Jianxia’s request, Jiang Yubai begins spending time with Tingwan to support her selective mutism. Though inexperienced and initially unsure how to interact with her, he listens to her written requests, explains interpersonal boundaries, and agrees to continue talking with her daily. 32 33 43 48

Appearance

Jiang Yubai favors simple, comfortable everyday clothing. His appearance can become notably disheveled after sleeping late, though he cleans up before visiting others. 16 37

Personality

Jiang Yubai is playful, provocative, and frequently careless with his words. He enjoys teasing Lin Jianxia when she becomes flustered, especially by calling her his “maid” or exploiting misunderstandings about their relationship. His jokes can be tactless, as when he insults Jianxia’s behavior to Tingwan or falsely claims his apartment has been rented out. 7 31 36

Beneath this flippancy, he is observant and more considerate than his reputation suggests. He notices when Jianxia is unwell, helps recover her unpaid wages, gives her stable employment without reducing it to pity, and accepts responsibility for helping Tingwan despite finding the request unusual. 16 19 21 43

He is also food-motivated and openly dissatisfied with his own cooking. His appreciation for Jianxia’s home cooking is a major reason he moves to Splendid New Village and hires her. 16 21
