He is the killer hidden in the deep building of another world. In the battle of blood and death, he burns his life like a meteor. She is the leader of a gang that has monopolized power. In the turbulent power struggle, she is struggling to move forward, walking on thin ice, and feeling extremely cold at high places. She was his belief, his pursuit, the only woman in his life, but he also hated her cold-bloodedness, her ruthlessness, her avoidance, and her retreat. Everything was due to her—that bright and happy girl. She changed his life, his beliefs, and his future. But since the roots of love have been planted deeply, there is no fear of wind and rain. No matter how much suffering and grudges there are, they will turn into tenderness in the interdependence of life and death. Since I have promised you this life, let me love you well for once.
