Sean (played by Zhang Xiaoquan) is a simple and kind boy who has been dating his girlfriend for many years and has a deep affection for her. However, what he never expected was that his loyalty was exchanged for the other party's ruthless betrayal. In anger and pain, Sean chose to leave. At the same time, his belief in love was forever broken. In order not to be hurt, Sean completely closed his heart. By chance, Sean met a cute girl named Emily (played by Zhou Dongyu). Emily's carefree, lively and cuteness gradually healed the scars in Sean's heart, and he began to try to believe in Emily and believe in love again. However, this time, Sean was disappointed again. It turned out that the seemingly innocent Emily hid a weird secret-she was a nail clipper demon who lived on eating nail clippers.
