In the gap between day and night in the city, Yan Xiaoxiao's 24-hour coffee shop is a gentle haven for returning home late at night. She used special coffee to soothe her tired soul, but she could not understand the emergency doctor Murong Chen who always gave coffee to homeless people. Murong Chen was insulated from coffee due to a caffeine allergy, but he was obsessed with her scalpel-like hands when pulling flowers - in his eyes, these hands should have saved lives under the shadowless lamp.
The misunderstanding fermented in the aroma of coffee until there was a sudden power outage in the emergency room on that rainy night. Yan Xiaoxiao rushed into the rain with a siphon pot, and while making tea for the doctors and nurses under the emergency light, the burn scar on her wrist was broken by Murong Chen. It turns out that this barista was once a piano genius, but a car accident caused the black and white keys to be replaced with coffee cups. Murong Chen silently wrote down everything and sent a special wristband with a coffee bean electrocardiogram printed on it: "Your heartbeat is my best prescription."
When the smell of disinfectant water and the aroma of coffee finally intertwined, two souls traveling through jet lag found a unique formula to heal each other.
