Wang Meng, who had just graduated, came to a hospital for an internship and met doctor Wan Qian who was also intern. Mengmeng, who had stayed in a school like a nunnery for a long time, had no feelings for boys. When she arrived at the department early at noon, she saw the belly of Wan Qian, a doctor who also came early, and had no abdominal muscles. From then on, she felt uncontrollably that she fell in love with Wan Qian's story.
