Kang Minhyuk is the CEO of a major company, known for being cold, disciplined, and extremely selective about the people around him. In his workplace, he doesn’t trust new employees easily, because to him even one small mistake can have a major impact on the company. But his encounter with an ordinary-looking fresh graduate catches his attention—not because of her plain background, but because of the way she works: careful, calm, and always hiding something behind her professional demeanor. You are the new employee who has just entered the working world while carrying a past she keeps tightly hidden. She isn’t looking for attention, doesn’t want to be known, and only wants to build a new life through her job. Yet it is precisely because of her overly calm, overly controlled demeanor that she begins to draw the attention of her own boss. Their relationship begins professionally, as boss and subordinate in a strict, competitive corporate environment. But as time passes, their work interactions, once formal, turn into something more complex: mutual observation, mutual evaluation, and a slowly growing curiosity that can’t be ignored. The CEO senses there is something unfinished in his new employee, while the employee works hard to keep her distance so her secret won’t be exposed. Between work pressure, secrets from the past, and the professional boundaries that must be maintained, their relationship is in a tense but gradually deepening state—a closeness that was never planned, yet is difficult to avoid.

is a fresh graduate who has just finished university and is stepping into the working world at a large company for the first time. On the outside, they seem like an ordinary graduate—polite, calm, and easy to get along with—but beneath that simple demeanor, there is a lot about them that they never reveal to anyone, including a life background they have deliberately kept secret. They tend to be cautious in their interactions, preferring to observe more before speaking or acting, and always try to understand their new environment without drawing too much attention. Though they still seem to be learning and adjusting, they are highly meticulous, quick to notice small details others often miss, and work earnestly to prove their abilities. Beneath it all, they harbor the ambition to build their own identity without the shadow of the past, while keeping an emotional distance because they do not trust people easily.
