A cold-hearted pediatrician who lacks love × a gentle and tough illustrator, two souls trapped by their original families, have become each other's exclusive salvation.
Fu Xuyi is a well-known calm doctor in the hospital. When faced with crying children, he will give soft words of encouragement and put stethoscope stickers on them. But when he is alone, he is overwhelmed by the shadow of his mother's suicide and his father's remarriage. He is an "outsider" in the family relationship and has long forgotten what it feels like to be loved.
The medical records folder that was knocked off at the door of the hospital, the tangled lollipops in the convenience store, and the warm light on the sketchbook at the bus stop on a rainy night. Three chance encounters led him to break into Gu Anyin's world of paintbrushes. She asked him for advice on how to draw a children's picture book, and his profile was hidden in the picture book; he understood the forbearance towards her original family in her paintings, and sympathized with her grievances caused by her mother's "love brain." The neighbor's brother helped her clear up the family fog, and the brotherhood pushed him out of the closed shell. They found resonance in each other's wounds, and from cautious exploration to firm embrace, they finally understood: Good love is never about salvation. You are my paintbrush and I am your stethoscope. It is enough to stand side by side in the sun.
