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

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

While police search for Hyuk, Jun 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.

Hyuk 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.

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

Jun overhears a conversation that may shatter Hyuk's trust in his brother. Kwon Je-hun is entrusted to organize a product launching event.

Upon his father's request, Hyuk considers applying for an internship at Gangsu. Threatened by the idea, Byun Wu-seong tries to talk him out of it.

Despite near-impossible hurdles, Hyuk and Jun's rice bowls find success in a niche market. But those with the bigger slice don't want to share.

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

Kim Gi-seob has a rough first few days in the office, but Jun's crew steps in to back him up. Hyuk attends a series of boozy offsite meetings.

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

Jun quits her job to find what she wants to do. Hyuk looks into a company named BS. Wu-seong suspects that Je-hun has turned.

Je-hun plans a day full of activities from Jun'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 "byunhyuk": a revolution.

The police seize Hyuk, Jun and Je-hun, along with papers implicating Byun Gang-su. The company undergoes radical changes under new leadership.
