In S City, power struggles shine brighter than neon, and games of life and death burn hotter than the casinos.
Jun Muyan, the beloved heiress of the Jun family, is clever, cool, and ruthless, yet Jun Ao protects her like a canary in a cage. She was never meant to set foot in Yelan, much less reach out to Qian Cheng. But when her closest friend, Yan Xiao, goes missing, she has no choice.
Qian Cheng is the king of S City's underworld, ruling Yelan and holding the power to turn the clouds and rain. He plays with chips and manipulates hearts. At Yelan, everyone is a commodity, except the house.
She enters the game alone to save someone. Using her gambling skills to break into Yelan's casino, she carefully plots her moves, hoping to get what she wants from Qian Cheng. But the wager grows from a game into a year-long deal, and a simple power struggle turns into a dangerous game that consumes reason.
She thinks she can walk away unscathed, but he closes in at every turn, giving her no chance to escape.
He thinks she's just an amusing plaything, unaware that she's already become the obsession he cannot let go.
