Youyou is the manager of a niche cultural and creative studio, and her life is like lukewarm boiled water. Until an unexpected project cooperation, she meets Shen Yu, an upstart in the investment industry who is regarded by the outside world as cold, distant and sharp-handed. He was used to controlling everything, but he made an exception for this girl who looked soft but had tenacity in her bones. From the initial purposeful approach to the unconscious heartbeat, Shen Yu used his own way to hold up the sky for Youyou, blocking the crisis in the studio and healing the scars of her past; and Youyou was like a warm light, melting Shen Yu's heart that had been frozen for many years. In the hustle and bustle of the city, the two went from testing to rushing, from "suitable" to "only", interpreting an urban love that is both the ultimate sweetheart and the pull of reality. They finally understood that the best "peerless boyfriend" is never a perfect person, but someone who is willing to let go of their guard for each other and spend the rest of their lives.
