17-Year-old Lin Wan wrote down her last wishes on her white hospital bed - to see the sea, raise a cat, and eat hot pot. Strangers send gifts every day with simple drawings of smiling faces. On the day I lost my hair during chemotherapy, a crooked crown appeared on the painting. On the day the list was completed, she waited for the bone marrow matching notification. Three years later, she walked out of the hospital with the orange cat in her arms. Sitting on the bench at the door was the man who always had his back to her. The sunlight passed through his empty sleeves, and she suddenly understood the small words under each smiling face: "Don't be afraid, I'm here." When she turned around, she met a pair of burning eyes.
