Ji Xingran and Shen Qiran met by chance during a city cat appreciation event, and started a humorous and tortuous urban romance by accident. Workplace pressure and family misunderstandings, youthful crushes and real-life challenges, the warmth of friends and self-growth are intertwined. Each volume uses independent events to advance the relationship between the two, whether sweet or sad, cleverly laying out jokes and warmth. Ji Xingran slowly doubts his own heartbeat, but as he faces the trivial matters of urban life together again and again, he realizes the true meaning of love - two different souls can get closer to each other because of resonance, and finally bravely face their hearts and achieve perfection in actions and choices.
