On a rainy night, Wen Yining, a 25-year-old floral therapist, rushed into the emergency building of the No. 1 City Hospital with a first-aid box-like box of flower materials - she wanted to deliver custom-made calming bouquets to children who were about to undergo heart surgery. At the elevator entrance, Gu Yanchen, a 32-year-old pediatric emergency doctor who was soaked all over, was running with the monitor in his arms. The cry of the child in his arms was in sharp contrast with his calm instructions. Wen Yining was hit and the flowers were scattered. In a hurry, Gu Yanchen only had time to say "ask the head nurse for reimbursement", but when he turned around, his eyes were caught by the sunflower disk she picked up - it was his mother's favorite flower during her lifetime.
