In order to get rid of the family marriage, the top killer Luo Wanquan (Q) got married to the "ordinary person" Ye Moyin, only to find that the person next to her was actually her ultimate assassination target - the underground emperor Pluto!
This marriage was a dragnet set by him from the beginning, just to lure her into the game and verify her identity.
When a hunter and his prey sleep together, every gentle touch may be a fatal temptation, and every sweet lie hides murderous intent. He issued a city-wide pursuit order, and gently warned her in her ear that "it's dangerous outside"; he set a dinner trap, and put on the most dazzling necklace for her.
In this ultimate game between husband and wife, love and murderous intent are intertwined, and trust and betrayal coexist. When the layers of disguise are stripped away, how should they face each other's true identities?
