Shy and introverted Eun Hwan-gi, who runs a public relations firm from behind closed doors, tries to work up the courage to meet someone he admires.

When a damaging news story worsens the misunderstandings surrounding Hwan-gi's behavior, he's placed in a new role at the company.

Upon joining Silent Monster, Chae Ro-un is shocked to figure out Hwan-gi's identity. The team receives its first client: an actor with a secret.

Ro-un glimpses an unexpected side of Hwan-gi when she follows him outside the office. The team's plans for a presentation run into a major hiccup.

Hwan-gi remembers the events of three years ago, when his secretary Chae Ji-hye fell in love with someone she could never be with.

After a video of Hwan-gi struggling to give a presentation goes viral, Silent Monster goes on a team-building workshop to try and build his confidence.

Ro-un decides she was wrong about Hwan-gi, who makes an effort to grow closer to his employees. Meanwhile, Kang U-il is pushed too far.

When U-il shows up in Malaysia, Ro-un notices a tension between him and Hwan-gi. While giving them space to reconcile, she loses her purse.

Ro-un wakes up in an awkward situation. U-il processes crushing news about Ro-un while the whole company finds out about his engagement.

When she's suddenly transferred to a different team, Ro-un isn't sure how to feel. Hwan-gi prepares for another nerve-wracking presentation.

Ro-un gets ready to tell Hwan-gi the truth about herself — and discovers he's been keeping his own secrets from her all along.

Ro-un's father is met with one cruel surprise after another. Hwan-gi urges U-il to come clean to everyone about his past mistakes.

On the day of their wedding, U-il takes out Eun I-su for one last date. Ro-un comes across a familiar drawing in U-il's office.

More truths are revealed as Hwan-gi recounts the events of the night Ji-hye died and I-su opens up to her loved ones.

While dealing with a painful new revelation about Ji-hye, Ro-un gets to work to try and save her father's barbershop from closing down.

Trouble at the company pushes Hwan-gi to step down. On a getaway with Ro-un, he's reminded that there's still a lot to learn about her.
