Code Name: Silver Rings, a top corporate spy, is given the high-stakes mission of retrieving the password to a vault containing the design for a groundbreaking quantum computer. The only problem? His target, the vault’s owner, has lost his memory in a car accident. Desperate, he infiltrates the man’s home, pretending to be his lover...only to discover that the password is hidden within the body of the target’s brother, Cha Wonwoo! As he searches for clues beneath Wonwoo’s clothes, tension builds, with Wonwoo growing increasingly suspicious. What begins as a cat-and-mouse game of seduction turns into a battle of trust and repressed emotions. In the end, will this intrepid mission end with a kiss...or a bullet? (Source: Lezhin)
