Office Affairs, Awkward Investigations & Unexpected Romance — tvN’s Filing for Love Is the K-Drama Rom-Com of April 2026

If your April K-drama watchlist still has room — and honestly it should — Filing for Love just dropped a teaser that screams chaotic workplace romance done right. Shin Hae Sun and Gong Myoung are already giving us the comedic duo energy we didn’t know we desperately needed.

Filing for Love Show — Overview

From Office Ace to Workplace Misconduct Investigator — Quite the Demotion

Meet Noh Ki Joon (Gong Myoung) — once the undisputed star of his company’s audit department, now unceremoniously demoted to Team 3, the squad that handles internal misconduct cases. And what kind of misconduct? Mostly workplace affairs. For a buttoned-up, by-the-book guy like Ki Joon, every new case is essentially a crash course in chaos he never signed up for.

Enter Joo In Ah (Shin Hae Sun) — his new team leader, described as tough, eccentric, and someone who’s very clearly hiding a secret. From the moment she assigns him to handle “PM business” (a euphemism for office romance investigations), Ki Joon’s perfectly ordered world starts unraveling in the most entertaining way possible.

The Teaser Has Already Delivered

The newly released teaser wastes no time establishing the show’s tone. Joo In Ah and Ki Joon move stealthily through the office like they’re on a covert mission, with In Ah dramatically declaring, “We have to catch them.” But it’s her follow-up line — “Let’s spend some meaningful time close together” — that sends Ki Joon into visible panic and viewers into instant delight.

This is the classic romantic comedy setup at its finest: two very different people, thrown together by circumstance, forced into close quarters — and the slow-burn tension that follows. What makes Filing for Love feel fresh is its workplace investigation premise, which gives every episode a built-in mission while the romance quietly simmers underneath.

Shin Hae Sun, best known for her standout performance in Mr. Queen, brings her trademark sharp comedic timing. Gong Myoung, who impressed audiences in Second Shot at Love, plays the straight man perfectly — which only makes the chaos around him funnier.
