Shihyeon, aka “Red Candy,” is a secret agent whose code name comes from bathing in the blood of his marks on dangerous missions. Shihyeon's tasked with seducing and obtaining intel from Hajun, a hot college professor. Shihyeon can disarm enemies but didn’t expect to be disarmed himself by Hajun’s own tight body. Now Shihyeon’s caught between loyalty to his spy agency and Hajun. Can Red Candy survive the incoming wave of enemies and still indulge in the sweet ecstasy of Hajun’s embrace?Stopping a fight Shihyeon says that unapproved sparring matches between agents are forbidden. Placing agent Alex into an arm lock Shihyeon adds that the use of sparring as an excuse to bully his inferiors and ends his sentence with the act of shoving him away. Shihyeon is known as one of the three SS-ranked agents at Vulture. Questioning if the data he received from the director is so important that he has to go there himself, hearing whether that is why he was ordered here Shihyeon thinks the director is saying he asks too many questions. As Agent "Red Candy" he accepts the instructions. With the assignment involving Park Hajun he wonders who the hell becomes a professor at his age. Sweating with nerves at seeing Park in the house Shihyeon wonders why he is here and why the bug he left on his front door did not warn him. His eyes swirl as Shihyeon considers what to do but remembering the details he proceeds to kiss Park in operation B: Honey Trap. Having stuck a bug and tracker on Park he means to silently follow him and not allow his face to be seen. Disarming someone following Park with a knife, Shihyeon manages to then notice and avoid a man wielding a taser gun. Considering it dangerous Sihyun then kicks at the man's leg to trip him. Sleeping with someone for a mission is not a rare occurrence but with Park it is Shihyeon's first time doing it with a man.
