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.

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.
