Yeon-su and Ung reunite for the first time in five years when she shows up at his door with a proposal to work together on an art project.

Eager to film a follow-up documentary, Kim Ji-ung sets out to persuade Yeon-su and Ung. But getting them to agree proves to be a challenge.

Yeon-su and Ung's squabbles begin even before the cameras start rolling. Ung refuses to dignify an infuriating plagiarism accusation with a response.

Ji-ung recounts how he and Ung became friends in their childhood. Yeon-su wants to apologize to Ung, but can't quite bring herself to do it.

Ung wakes up on the morning of the live drawing show with a few gaps in his memory. Watching him at work, Yeon-su sees an unfamiliar side of him.

A forced vacation commences for Yeon-su and Ung when the documentary crew traps them at a mountain retreat. Awkward tensions run high between the pair.

When she doesn't hear from Ung after their return from the retreat, Yeon-su decides to confront him. He has a disorienting response for her.

With his mother back in town, Ji-ung stops going home so he can avoid seeing her. Watching NJ and Ung go on a date vexes Yeon-su to no end.

Ahead of the final day of filming, gossip about Ung and NJ causes a stir. Ji-ung receives pointed advice about his documentary edit.

For Ung and Yeon-su, a new beginning is equal parts sweet and clumsy. When NJ bumps into Ji-ung, she invites him out for a drink.

After soliciting dating advice from a co-worker, Yeon-su acts out of character in front of Ung. Meanwhile, Ji-ung takes some time to himself.

A noticeably down Ji-ung pours himself into his work instead of going home. Ung waits for Yeon-su to come and see the final night of his art exhibit.

Ready to pursue his next dream, Ung sets his sights on studying overseas. When he asks Yeon-su to join him, she has a tough decision to make.
