Marketing Team 3's official troublemaker Lee Sang-sik faces a crisis when the video celebrating Gaus' 50th anniversary, which he uploaded only to his private channel, is released publicly without his knowledge. Along with the chairman's prosecution summons, his actions trigger a storm that threatens the team's survival.

Cha Na-rae and Lee Sang-sik, sworn enemies, become coworkers and neighbors, setting strict boundaries between them. But anyone who crosses the line faces the consequences. Meanwhile, Kang-mi is shocked when her dream kiss partner appears in real life, and a mysterious new employee, Baek Ma-tan, joins Marketing Team 3. But is he really a newbie?

Sang-sik decides to make his 10th confession of love to Hae-young, whom he has crushed on for five years. However, his plan unravels when Hae-young catches him hugging his fiery next-door neighbor (and coworker) Cha Na-rae.

Lee Sang-sik learns that Hae-young has a boyfriend but decides to clear the air by confessing his feelings to her anyway. Meanwhile, Kang-mi accidentally overhears that Ma-tan is the corporate successor, leaving Ma-tan terrified that her famously loose lips will expose his secret.

Na-rae hears a rumor that Sang-sik has fallen for someone and can't help wondering if she's the one. Could it be true? Meanwhile, "kirogi father" Manager Wi eases his loneliness with an AI speaker and soon becomes so attached that he can't bear to be without it.

Na-rae is fed up with getting hurt every time she's around Sang-sik and even files a restraining order to keep her distance. While recovering with Aziz's help, she makes a surprising discovery. Meanwhile, after being criticized for writing an apology like a novel, Moon-hak throws himself into the Gaus Massage Gun event to redeem himself.

Lee Sang-sik sends an apologetic text and goes on a blind date after a reckless kiss, which makes Cha Na-rae furious, while a hidden spy starts causing trouble at work.

Lee Sang-sik and Cha Na-rae hesitate to define their relationship after two uncertain kisses. Meanwhile, Baek Ma-tan's heart races after he witnesses Gun Kang-mi's fierce 17-on-1 street fight.

Sang-sik and Na-rae start dating in secret, but Na-rae worries their teammates will find out. Meanwhile, shocked by his first paycheck, Ma-tan experiences working-class life with Kang-mi and decides to buy a gift for someone special.

After spending his housing deposit on a street lamp for Kang-mi, Ma-tan finds himself homeless and turns to Sang-sik for help, with his fiancée, Oh Ro-ra, following close behind. Meanwhile, Na-rae becomes more assertive, and her relationship with Sang-sik takes an unexpected turn.
