In the bustling city, there is a girl named Lin Wan, who has a stable job and a warm life. In her world, everything is so perfect until she meets her boyfriend's cousin.
Lin Wan's boyfriend, Zhao Yu, is a gentle and elegant man with a successful career. They met at a chance party, and Zhao Yu's maturity and thoughtfulness quickly touched Lin Wan's heart. Soon after the two met, they fell in love. In the eyes of their friends, they are a pair of lovers made in heaven, with deep and enviable feelings.
However, just when Lin Wan was immersed in a happy love, an unexpected encounter broke her peaceful life. It was a weekend afternoon, when Lin Wan and Zhao Yu were shopping together, they happened to meet Zhao Yu's cousin, Li Hao. Li Hao is young, but he already has his own company, and his career is booming. He is handsome and imposing, which is hard to ignore.
When they first met, Li Hao showed a strong interest in Lin Wan. He took the initiative to talk to Lin Wan, asked her about her work and life, and even showed a strong interest in her hobbies. Li Hao's enthusiasm and sincerity made her irresistible. She couldn't help but start keeping in touch with Li Hao, and gradually, the relationship between the two became closer and closer.
Until one day, Lin Wan accidentally discovered a piece of Li Hao's intimacy with other women**. She was shocked to find that Li Hao actually maintained an ambiguous relationship with multiple women at the same time. Lin Wan felt as if she had been betrayed, and she couldn't accept this fact. She questioned Li Hao, but Li Hao lightly said that it was just a part of his life, and he didn't care about Lin Wan's feelings.
Lin Wan felt heartache and helplessness, and she began to re-examine her relationship with Zhao Yu and Li Hao. She discovers that although Zhao Yu has never betrayed her, his complicated attitude towards Li Hao makes her feel uneasy. She began to wonder if Zhao Yu had a similar problem, and if their relationship also hid an unknown secret.
In the midst of pain and struggle, Lin Wan decided to be honest with Zhao Yu. Zhao Yu was silent for a long time, and finally confessed his past to Lin Wan. He used to start a business with Li Hao, but because of Li Hao's selfishness and betrayal, their career failed, and Zhao Yu was also burdened with huge debts. He was well aware of Li Hao's misconduct, but because of family reasons, he had to keep in touch with Li Hao. He assured Lin Wan that he had never betrayed their feelings, and he also hoped that Lin Wan would give up contact with Li Hao.
Lin Wan listened to Zhao Yu's confession, and her heart was mixed. She felt both relieved and moved, but also helpless and confused. She self-destructs for her loss and decides to live well with Zhao Yu.
