Jiangcheng city is full of fireworks and the pace of life is leisurely. The heroine Cen Xiaoxiao is a primary school Chinese teacher. She is sweet-looking and smart. She can't walk when she sees handsome guys, especially tall men with cold faces. One day during a physical examination, she met Xiao Ruiyuan, a cardiac surgeon from the First Hospital of the City. He looked like someone who stepped out of an ancient painting. As soon as he put on his white coat, his eyes dropped, and his aura said "Don't get involved". But Cen Xiaoxiao got involved. She ran to the hospital when she had nothing to do. Today she complained of palpitations, tomorrow she complained of insomnia, and the day after tomorrow she even took the whole class of children to do health science popularization, just to see him more. Dr. The two of them slowly get closer to each other in their daily interactions. One is boldly flirtatious and a drama queen, while the other is superficially abstinent and secretly jealous. The story unfolds easily in the human fireworks of this city, with no bloodshed, only heartbeats and laughter.
