Given up on becoming a pro board game player, Jang Geu-rae is now an intern struggling to handle corporate life, reliant on his coworker Ahn Young-yi.

Working alone after hours, Geu-rae finds he is isolated from his coworkers despite his boss’s advice on teamwork. Talks of a co-presentation come up.

After revealing Park’s misconduct, Oh is promoted to deputy manager. The 3rd Sales division’s new chief is Chun Kwan-woong, who intimidates Geu-rae.

Geu-rae once again remembers that he is the only intern among his peers. He asks Oh if he can become a permanent employee.

The Director offers the 3rd Sales division a major project, but Oh is suspicious. Kim Dong-shik gets into an argument with coworkers who insulted Oh.

The 3rd Sales division is uneasy after Geu-rae voices suspicions about the Director’s project with Seok. The head office launches an investigation.

After the turmoil, the 3rd Sales division finally returns to normal. A new boss arrives with new methods. Meanwhile, Geu-rae’s contract nears its end.
