Episode one opens on Kevin's private resolve to pull Olympias apart from the inside, then his pitch to Luna: he knows he is the only person in the room who can carry the weight of her power. She appoints him personal assistant and immediately questions who he really is.
Episode two puts him into the project workflow: send the plan to PR, and any misstep falls on Kevin. Luna notes her hands are cold and her heartbeat betrays the performative poise, while the board keeps speed on the project.
Episode three surrounds the private safe, which has never triggered an alarm before Kevin's arrival. At the charity gala Marcus warns that strength usually brings a weak spot, and that Kevin's father learned that lesson the hard way; Kevin positions himself as Luna's right hand and her sharpest blade.
A designer working under a revenge motive tied to his father's downfall, Kevin talks his way into Luna's office by claiming he can carry her power. He keeps his real identity concealed while handling the board's pressure and the private-safe mystery.
Because I know I'm the only one in this world who can carry the weight of your power.
Head of Olympus Group, Luna keeps her outward calm even when her cold hands and quick heartbeat give away tension. She gives Kevin the assistant role, leans on him at the charity gala, and keeps probing his identity in private.

Our editors' notes on the opening arc — personal picks, not audience feedback.
"The interview doubles as a duel: Kevin sells competence and nerves in the same breath, and Luna's question about his real identity hangs over the whole assistant arrangement from the first minute."
"The safe alarm and the gala warning convert office drama into a slow-burn investigation. The right-hand-and-sharpest-blade line frames Kevin's cover as loyalty while his revenge plan stays half-hidden."
Best for viewers who like corporate suspense with an undercover assistant, a cold CEO, and a family-revenge motive; if you want open romance early, the opening episodes keep attraction buried under caution. Compared with most workplace shorts, this one runs the revenge and the slow-burn through projects, a safe and a gala rather than a plain rivalry tournament, which is both its strength and its limit.
