In the spring of 2001, Lin Qi, an abandoned baby with "type O negative blood" written on it in a Beijing hospital, was adopted by the Meng family who were eager to save their daughter. From then on, she existed only for one person - Meng Nian'an, the real daughter of the Meng family. She is a mobile blood bank, a backup of organs, and a shadow without a future under the exquisite egoism of the Meng family.
Fifteen years later, Lin Qi is already a taciturn top student who regards his studies as the only way to escape. Until she met Gu Yanchi, a young man who was also exiled by his family and used violence as armor. An "equivalent exchange" that began with the unexpected gift of milk and notes brought two lonely souls closer in the cold.
He bumped into her most embarrassing secret and clumsily handed over a box of band-aids; she saw through his cynical self-destruction, stubbornly made up for him and said, "You can do it." They held an umbrella together in the rain, shared their heartbeats on the back of a motorcycle late at night, and tasted the feeling of "being cared about" for the first time in each other.
However, when Meng Nian'an's condition becomes critical again, when the new pinhole on Lin Qi's arm is discovered by Gu Yanchi, when the heavy adoption contract collides head-on with the boy's hot heart - can the tiny fantasy about the future that she carefully constructed, and his newly trying to straighten his spine, survive the crushing impact of reality?
