A group of young boys and girls with different personalities meet in the hospital due to serious illnesses. Guided by the belief that "my fate is determined by me, not by heaven," Cheng Hui, "first-time cancer patient", and Lu Yu Qing, a "sickly overachiever", come together under the advocacy of Tie Yi, a "long-term patient." They support each other, using optimism and sardonic humor to fight against their illnesses. Despite facing critical life changes at a young age, the youths bring their unique vibrancy and positive spirit to those around them— like the cool and tough Li Zong, who has ovarian cancer; the quiet boy Tian Ran, who has autism; and Tang Tang, who is in a vegetative state due to bullying. They seek happiness amid harsh realities and look forward to sunny days ahead, buoyed by their youth and each other's companionship.
