Drunk and broken-hearted, Byeon Hyeok gets into a scandalous accident on a plane. Baek Joon is accused of stealing while on duty at a luxury hotel.

When the footage of the plane incident goes public, Hyeok is in the hot seat. He tries to make things right, only to have his father squash his efforts.

While police search for Hyeok, Joon steps in to smuggle him out to safety. She gets him a job, but the rich boy can't seem to stay out of trouble.

Hyeok turns himself in to the police, unaware of the work he's undoing. Upon release, he's kicked out of the house stripped of clothes and resources.

Hyeok follows Joon on her way to work one morning and ends up joining her cleaning crew. Their first assignment takes them to Gangsu Group's headquarters.

Joon overhears a conversation that may shatter Hyeok's trust in his brother. Kwon Jehoon is entrusted to organize a product launching event.

Upon his father's request, Hyeok considers applying for an internship at Gangsu. Threatened by the idea, Byeon Wooseong tries to talk him out of it.

Mr. Jang moves Hyeok to find a win-win solution to end Gangsu's exploitation of small factories. Meanwhile, Jehoon steps in to nip the case in the bud.

A shocking revelation concerning Joon's father causes her to fall off the radar. Hyeok finally sees the lengths his brother is willing to go to win.

Kim Giseop has a rough first few days in the office, but Joon's crew steps in to back him up. Hyeok attends a series of boozy offsite meetings.

Facing accusations from his brother, Hyeok has three days to prove his innocence. To get a hold of hard evidence, Joon recruits an unlikely spy.

Joon quits her job to find what she wants to do. Hyeok looks into a company named BS. Wooseong suspects that Jehoon has turned.

Jehoon plans a day full of activities from Joon's bucket list. What she doesn't know is that this is his way of saying goodbye.

Gangsu Group retaliates against corruption charges by firing their employees. But the groundwork's already been laid for a "byeonhyeok": a revolution.

The police seize Hyeok, Joon, and Jehoon, along with papers implicating Chairman Byeon Gangsoo. The company undergoes radical changes under new leadership.
