Su Guugu, a girl who died in the war three thousand years ago, unexpectedly woke up in the 21st century city in the form of a skeleton. With no body, no breathing, and only a white skeleton, she not only has to evade the pursuit of the "Abnormal Biology Bureau", but also struggles to adapt to a completely unfamiliar modern life - afraid of the sun, moisture, and osteoporosis, and carries tons of high-calcium milk every day; she wants to pretend to be a normal person, but always loses her chain at critical moments: wearing a wig is blown away by the wind, wearing clothes that expose her joints, and even being ignored by the elevator sensor because she is too light.
In an accident, she met Lu Shiyan, a pet doctor who was cold on the surface but soft on the inside. Lu Shiyan looked at the "special creature" in front of him that could talk and "blush" (the skull's eye sockets shimmered), and was forced to start the funny daily life of "raising skeletons". He bought her a sunscreen umbrella, a custom-made anti-fall skeleton protective cover, taught her how to use a mobile phone and go to the supermarket, while Su Gugu warmed him in his own way - rapping a lullaby with his joints when he was working overtime, and clumsily using his ribs to pass tissues when he was sad.
From the initial mutual wariness to the gradual dependence, Su Gugu, with the help of Lu Shiyan, experienced the fireworks of the world bit by bit: drinking milk tea for the first time, watching a movie for the first time, and feeling the warmth of a friend for the first time. She began to long for the feeling of being "alive" and to truly embrace the people around her. Lu Shiyan also gradually took off his disguise while getting along with Su Gugu, and found the long-lost happiness. This funny love that spans life and death and breaks the boundaries of species is quietly heating up in the corners of the city, hiding delicate tenderness and enthusiasm for life.
