Seventeen-year-old Tang Zhi is terminally ill and was slapped out of the house by his brother Tang Yu due to a misunderstanding. She left home with her family portrait. She was seriously ill but did not want her brother to be sad, so she deliberately pretended to be free and easy. Although Tang Yu said he was indifferent, he had already noticed that his sister was abnormal, but he did not dare to delve into the truth. A fainting with a nosebleed became an opportunity for the two to say goodbye forever. Tang Yu later realized all the misunderstandings and finally realized her good intentions. In the end, amid endless regrets and hallucinations, he ushered in a belated reunion with Tang Zhi, who had already passed away, in another time and space.
