The neon lights of Xinghai City have illuminated the loneliness of countless people, and also hide the unexpected tenderness.
She is Su Wan, the owner of an independent bookstore on the verge of bankruptcy. She carries family debts on her thin shoulders, but she hides her dream of painting among the pages of her books. He is Lu Chengyu, an upstart in science and technology. He is used to building the world with codes and data. The shadow of his childhood has made him build high walls. He does not believe in weaknesses, let alone love.
An unexpected collision in a heavy rain unexpectedly intertwined people from two worlds - she hit his car to save a stray cat, and he became a frequent visitor to her bookstore to recover compensation. From the initial tit-for-tat confrontation, to him seeing tenacity in the pages of her book, and she discovering softness in his coldness; from careful probing, to retreating when feelings secretly arise, they clumsily learn to get closer in the fast pace of the bustling city.
The heavy pressure of family debt, the sudden attack of corporate crisis, and the entanglement of the shadow of the past push them away time and time again. But when she picked up the paintbrush again and bloomed with light on the canvas; when he took off his armor and learned to measure emotions with temperature instead of data, he realized that the deepest bond is to be able to stand side by side against the edges and corners of life, and to find his own light in each other's eyes.
This is a story about redemption and growth. In the bustling city, two lonely souls meet and collide, and finally, in the depths of neon, they confirm that each other is the warmest destination in life.
