Lu Mingxi and Yan Chengxing, two children who grew up in an orphanage, have a common dream and a common struggle. When their lives are closely linked by the doctor's sentence, "You don't have many days left..." If fate does not favor them, where will they go? Should we fight against the disease, or accept our fate?
