Zhou Han, who thought life was gloomy, embarked on a journey to 1997 with her "agent" Zero. Their lives are full of endless regrets. Can this journey to make up for regrets reverse fate, or is it just a dream? And everything they did was just to make up for their own regrets? I met you somewhere, and I looked at you from afar in the shadows. Love is never one-way, just like I saved you without knowing it.
"Perhaps you are better suited to be an agent than me."
"Perhaps you are better suited to be a friend than an agent."
Intention: Just be your happy self without restraint. Life may come to an end, but happiness and hope will always be infinite.
