Behind the Scenes of Diary of a Prosecutor: Lee Sun-kyun’s Playful Chemistry and Hidden Easter Eggs

Diary of a Prosecutor (2019), the legal dramedy helmed by director Lee Tae-gon, may have flown under the radar for some international audiences, but its sharp wit and standout performances—particularly from the late Lee Sun-kyun—have kept fans buzzing. latestnetflix.com's take is that while the series itself blends workplace satire with procedural drama, a few behind-the-scenes tidbits and on-set moments have surfaced, offering a glimpse into the cast’s chemistry and the show’s creative choices.

Lee Sun-kyun and Jung Ryeo-won’s "Café Coupon" Moment

One of the most talked-about behind-the-scenes clips involves Lee Sun-kyun, who played the earnest prosecutor Lee Sun-woong, and Jung Ryeo-won, his sharp-witted colleague Cha Myung-joo. In a lighthearted epilogue video , Sun-kyun is seen playfully coveting a café coupon Jung’s character had in the show. The clip, titled "Lee Sun-kyun Coveting Jung Ryeo-won's 'Cafe Coupon' (Ah~?)", captures the actors’ off-screen camaraderie, with Sun-kyun’s exaggerated reactions drawing laughs. While the video doesn’t reveal much about the show’s production, it underscores the easy rapport between the two leads—a dynamic that likely translated into their on-screen partnership.

**A Nod to *In the Mood for Love***

For cinephiles, Diary of a Prosecutor dropped a subtle but deliberate Easter egg. A YouTube video highlights a scene where the series visually references Wong Kar-wai’s In the Mood for Love, mirroring its iconic slow-motion shots and muted color palette. The homage isn’t just a stylistic flourish; it reflects the show’s occasional melancholic undertones, contrasting with its otherwise comedic tone. Whether this was a directorial choice by Lee Tae-gon or a suggestion from the cinematography team remains unclear, but the reference adds a layer of depth to the series’ aesthetic.

On-Set Bloopers and Cast Dynamics

Another behind-the-scenes clip —this one from episode 8—shows Lee Sun-kyun playfully teasing co-star Lee Sung-jae (who played the seasoned prosecutor Han Min-ho) about a prop. The snippet, titled "Lee Sun-kyun Showing Off [Yucheok] to Lee Sung-jae (It’s Ruined;;)", suggests a relaxed set where the cast didn’t take themselves too seriously. While the context of the "Yucheok" (a term that could refer to a prop or inside joke) isn’t fully explained, the clip hints at the kind of playful banter that likely made long shooting days more bearable.

What We Still Don’t Know

Despite these glimpses, Diary of a Prosecutor’s production remains largely undocumented in English-language sources. There’s no confirmed word on:

• Episode count or filming timeline: The SERP evidence doesn’t specify how long production took or how many episodes were shot.
• Behind-the-scenes tensions: Unlike some K-dramas, there are no rumors of on-set conflicts or creative disputes.
• Director’s vision: Lee Tae-gon’s background as an actor-turned-director suggests a hands-on approach, but details about his process for this series are scarce.

For now, the most compelling behind-the-scenes moments are the ones fans have pieced together from promotional clips and epilogue videos—small but telling windows into the show’s lighter side.
