Shen Yubai, a university philosophy professor, once quietly suppressed her brilliance for the sake of a seven-year relationship. When she discovers that the promises she once believed in were nothing but empty words, she refuses to waste herself on the past and chooses to start over. She leaves for a research visit abroad, devoting herself to the academic pursuits and career she loves. In the old bookstores and art galleries of a foreign land, she not only enters a brilliant new chapter in her career but also meets a kindred spirit who understands her and accompanies her in exploring the world.
