Marketing Team 3's official troublemaker Lee Sang-shik has hit trouble as the video commemorating Gaus' 50th anniversary has been made available to the public without his knowledge.

The enemies meet at work, not on a single-log bridge. Cha Na-rae and Lee Sang-shik, who despise each other, not only sit next to each other at work but also live next door.

The day Lee Sang-shik decides to make his 10th confession of love to Hae-young, whom he's had a crush on for five years, Hae-young sees him hugging her next-door neighbour, Cha Na-rae.

Lee Sang-shik knows that Hae-young has a boyfriend and wants to smoothen everything up. He confesses to Hae-young. Meanwhile, Kang-mi overhears that Ma-tan is the successor to power.

If Lee Sang-shik and Cha Na-rae don't fight for a day, they get thorns in their mouths. At the office, Cha Na-rae hears that Lee Sang-shik has a new person he loves.

Cha Na‑rae fights her growing feelings for Lee Sang‑shik as being near him causes injuries and nosebleeds, so severe she files a restraining order, fearing it might kill her.
