Chateau boards a luxury cruise ship for a mission. There, she runs into Ryang-ha, who makes things difficult for her once again. They spend a night in a room together, in part so that Chateau can keep an eye on him.

Chateau tries to determine Euripedes' whereabouts, but is bothered by Ryang-ha's suspicious behavior. He lets a mysterious attacker escape, and when he meets with Chateau, she pulls out a gun.

Chateau leaves herself with Jinon and his associate, Nikka, in order to carry out her operation. Meanwhile, both the boss and Jim are put in danger.
