Lu Zhaozhao, an executive at a small company, struggles for three months to secure a contract and finally makes it to a business dinner with the client. To her surprise, the client, Lu Jingchuan, turns out to be her own brother, with whom she constantly bickers. She openly trades barbs with him in front of everyone and gets him to promise special perks for her team, making her colleagues see her as their ultimate protector. Her boss, Li Shu'an, mistakenly believes Lu Jingchuan is giving her a hard time and is even willing to abandon the deal to stand up for her. Lu Jingchuan later arrives at the office with the contract, and after several misunderstandings, the truth about their sibling relationship finally comes to light. Li Shu'an joins the Lu family for a meal and unexpectedly discovers that the family has arranged for him to be Zhaozhao's blind date. He begins actively pursuing her, but Zhaozhao, still recovering from heartbreak, keeps her distance. When her ex shows up to cause trouble, Lu Jingchuan has already dealt with his misdeeds, and Li Shu'an also steps forward to protect her. In the end, Zhaozhao joins her colleagues on a company cruise and finally lets go of the past.
