The K-drama Mr. Plankton took Netflix by storm with its heartfelt story, quirky characters, and emotional finale. Since its debut on November 8, 2024, fans have been buzzing with questions about whether Hae-jo and Jae-mi’s journey will continue. With a mix of romance, comedy, and deep themes, the show left viewers craving more. So, is Mr. Plankton Season 2 on the horizon? Here’s a deep dive into everything known so far.

The Story of Mr. Plankton Season 1

Mr. Plankton follows Hae-jo (Woo Do-hwan), a man grappling with a terminal brain disease and a lifelong search for his biological father. Alongside him is Jae-mi (Lee You-mi), his ex-girlfriend, who’s navigating her own struggles as the “unhappiest bride-to-be.” Their road trip across Korea is filled with heartfelt moments, humor, and revelations. The season’s finale hit hard, wrapping up with Hae-jo’s emotional farewell under a “dazzling blue sky” and Jae-mi by his side. The story felt complete, but its open-ended nature has sparked hope for more.

Has Netflix Renewed Mr. Plankton for Season 2?

As of August 2025, Netflix hasn’t dropped an official announcement about Mr. Plankton Season 2. The show was marketed as a limited series, which often means a one-and-done story. Many fans feel the finale tied up the main arcs beautifully, leaving little room for continuation. However, the K-drama’s massive popularity could sway Netflix to greenlight another season.

Some sources, like whenetflix.comclaim a second season is set for November 7, 2025, with 10 episodes. This report mentions returning cast members like Woo Do-hwan as Hae-jo and Lee You-mi as Jae-mi, along with a teaser trailer. But here’s the catch: no official confirmation from Netflix backs this up, and other sources contradict it, calling the show concluded. Until Netflix or the creators confirm, treat these claims as rumours.
