Thirty-two-year-old Xu Zhiyi is considered by others to be an independent and strong-willed working woman. She is also a single aristocrat who embraces celibacy and never touches love. She worked hard to build a career, but the world did not judge her fairly - "A woman in her thirties, no matter how good her career is, she is still not an older leftover woman that no one dares to want." She built a wall in her heart, rejected all tenderness, and just wanted to be alone until she met Jiang Yuchuan. The talented young designer who was six years younger than her, despite all rumors and prejudices, was moved by her charisma and made the most sincere confession under the stars. He didn't care about the age difference, he only cared about her as a person. Can this sincerity change the original intention of this single person, the resistance of the family, the prejudice of the world, the harassment of the ex-boyfriend, and the many obstacles, can the brother and sister have a happy relationship and spend the rest of their lives together?
