Freshly graduated from college, Lydia joins the Blackwood Group. On her very first day, she catches her fiancé Ryan cheating with another woman in the office. That same day, she accidentally sparks a connection with a stranger named August in the elevator. Little does she know, this man is the company's reclusive CEO who never shows his face.
Heartbroken over her breakup, Lydia starts a secret romance with August. She thinks he is just an ordinary employee at the company. Meanwhile, her fake best friend Sophie has people bully her behind her back: spreading rumors that she climbed the ladder by sleeping around, cornering her late at night, and drugging her drink. Every time Lydia falls into a desperate situation, August shows up in time — the people who bullied her get fired the next day, but she never finds out who exactly is protecting her. At Sophie's birthday party, Lydia is drugged and almost taken away by several men, but August saves her just in time. It is on this day that Lydia learns the man she has fallen in love with is actually her best friend's father. Wracked with guilt and inner conflict, she writes a resignation letter to run away, but he stops her again and again, and the two sink deeper into their relationship.
