In the silent world hidden under happiness and peace, there is only endless blood and cruel killing. The dark organizations hidden in the light, silently and without a trace, are doing despicable things. A person with a bright future and a life full of sunshine is involved in this dispute. The hope in her eyes was gradually overshadowed by despair. Her dearest person in the world was the "messenger" of this dirty world, and the culprit who pushed her ruthlessly into this abyss. No matter how hard she struggled and tried, she could never escape the fate that had been arranged for her. The gentle eyes in the past were now filled with anger and cruelty, and could no longer tolerate that tenderness. Maybe it's true that I no longer like the light after getting used to the darkness. If you can't go back, just move forward. Will the gear of fate favor her? How will her life continue?
