His Xiao Qingmei is Super Fierce

Yi Qianqian, eighteen years old, is forced by her parents to stay at the villa of her fiancé Tan Mobai after they trick her into believing they are going on a trip. She and Tan Mobai have been childhood sweethearts but despise each other due to a forced engagement arranged when they were eight. Arriving at the villa in winter, she finds no one answers the door and eventually yells for him. Tan Mobai watches her from inside and initially refuses to let her in until his mother calls ordering him to take her in. He reluctantly allows her entry but releases a Tibetan Mastiff to scare her, though the dog is familiar with her. That night, Tan Mobai receives a call from Han Du'er, a woman he knows, who is drunk and distressed at Huangyu, an entertainment venue. He goes to rescue her from several men and brings her back to the villa for one night. Yi Qianqian, already on her period, is furious when she sees Han Du'er at the door and confronts her, telling her to leave. The next morning, Tan Mobai sends Han Du'er back. He treats Yi Qianqian coldly but shows some concern when she has cramps. Yi Qianqian feels trapped by the situation, disliking him and the engagement. After a call from her mother confirming she cannot return home and her card is cut off, she decides to move out. She ignores Tan Mobai's indifference and leaves the villa with her suitcase, despite Song Steward's attempts to stop her. She takes a taxi to her close friend Lin Feifei's home. Lin Feifei is working a part-time job at an entertainment venue as a cleaner during winter break. When Yi Qianqian arrives, Lin Feifei returns from work. Yi Qianqian decides she wants to work with Lin Feifei to earn money, as she has no financial support and refuses to depend on Tan Mobai. The story establishes the central conflict of a forced engagement, the antagonistic relationship between the protagonists, and the introduction of a rival figure Han Du'er. It ends with Yi Qianqian starting a new independent life away from Tan Mobai, seeking her own means to survive.
