After staying up late in the summer, the social animal died suddenly and was reborn. When he graduated from college, he decided to use all his savings to buy an early-morning stall in a village in the city and founded the "Yeguiren Canteen" to provide healthy meals to people working the night shift. Gu Xing is a cardiac surgeon at a top hospital. He collapsed in front of her stall due to consecutive surgeries. After waking up, he became her first "guest nutrition consultant". The two combined medical data with home-cooked tastes to create a mobile food truck chain, shining a light on late-night workers in the city. In countless sober mornings, they used food to heal their running bodies and minds, and also to make the extinguished heart beat for one person again.
