This is a modern urban novel written from a female perspective and with multiple female growth lines intersecting in parallel. Lu Mingtang, a grassroots man, Lin Qingwei, a white-collar elite, and Song Jiayi, an artistic young woman, have been with each other for more than ten years since they met in college. They struggle, wander, or pursue their dreams, and experience various impacts on career, relationship, family, and self-identity. The book uses humorous dialogues, clever misunderstandings, and urban strange circles to secretly connect each other, and progresses layer by layer. Reverse the crisis in laughter, grow in tears, and finally use wisdom and courage to bloom your true youth. The book is divided into four volumes, from youthful beginnings, ups and downs of struggle, fission and growth to self-reshaping, echoing back and forth, with magnificent waves.
