The killer Ling Ye, codenamed "Shadow", disguised himself as "Azhe" with an assassination mission and infiltrated the gang leader Cui Chengyu. It was originally a confrontation between the hunter and the prey, but in the day after day of temptation, he was shaken by the tenderness under the domineering side and the weakness under the cruelty.
Cui Chengyu had already seen through the disguise, but he indulged in this approach and watched him struggle between work and love. Zhao Shanhe's threat, the past in the orphanage, and the appearance of the real "Azhe" drew the two into a deeper whirlpool. When Ling Ye confessed, "I came to kill you," Cui Chengyu held his hand: "I'm waiting for you to choose me."
From facing each other at gunpoint to fighting side by side, from pretending to test to staying together in despair. In the throes of transformation of the Blue Dragon Society, the killer lost his coldness and the boss let go of his control. When the shadow of the past catches up with him, Cui Chengyu uses the entire gang to pave the way for him: "I will settle the past, and the future... Will stay with me."
This entanglement that started with hunting ended up being mutual salvation. Concerns are hidden in the light of swords and shadows, and the gangs are guarding each other. The two lonely souls finally find the shore where they can dock.
