Song Tiantian is a patient with congenital myocarditis, a female writer who has been in the Internet literary circle for five years and is still unknown. During another re-examination, I met again Wu Zifan, a boy I had a crush on for three years in high school. When I met again, Wu Zifan was already a cardiologist and became a colleague with Song Tiantian's college roommate Yuan Yun. I met again and Song Tiantian became Wu Zifan's patient. A series of stories happened, and finally the story of the two of them together.
