They are the brightest light in each other's lives, but they are destined to be separated in the darkness. Su Yan once thought that love is a desperate rush.
Su Yan was an accident that broke into Gu Yanchen's delicate life. She is emotionally hot, and he is rational and cold. People from two different worlds fell in love under the neon lights of the city. However, the brighter the light, the darker the shadow. They are lovers and have become enemies who know each other best. Finally, at the rainy intersection where they met, they stopped in silence, with no one taking another step forward. Su Yan extinguished the last light in his heart with his own hands and walked into the sea of people without him; Gu Yanchen, standing in the world he owned, realized that he had lost his only bright color forever. The most painful thing in the world is not not seeing the light, but knowing that you are my light, but having to let go and let each other sink into the eternal night.
When betrayals, misunderstandings, and reality ensue, the light finally begins to flicker. They struggled, pulled, hurt each other, and spent countless late nights making excuses for each other. They are the closest lovers and the enemies who know each other's weaknesses best.
In the end, at the intersection where they first met in the cold rain, separated by the constant flow of car lights and crowds, no one took another step forward. Su Yan understood that there was some darkness that even light could not penetrate; Gu Yanchen also realized that in the order he had guarded all his life, only his most cherished "accident" could not be tolerated.
