On a long winter day, the idea of "death" creeps into Yang Yang’s young heart. When longing transforms into poetry, memories endure eternally in the form of light and shadow.

Welcome to Ward 816, a place filled with incredible children who are true warriors. Each of them carries a badge symbolising their strength in fighting various diseases. In this bustling ward, there's a special group, including Yuan, Shi-yan, Heng, Nuala, Jia-nong, and Da-shan. Despite their parents' occasional arguments, they always come together to support one another when it matters most.
