Series: Mr. Plankton -2024- Web

Woo Do-hwan delivers a career-best performance as Hae-jo. He is not a sweet, protective male lead. He is prickly, volatile, and sometimes cruel. He lies, he manipulates, and he openly admits he’s not a good person. Yet, Do-hwan’s performance reveals the terrified, lonely boy underneath the bravado. You root for him even when you want to shake him.

The indie-influenced OST, featuring songs by artists like Kim Feel, perfectly captures the bittersweet tone: hopeful yet deeply melancholic. You should know going in: Mr. Plankton is a tragedy wrapped in a rom-com’s clothing. The terminal illness is not a plot device that magically gets cured. The show commits to its premise. Mr. Plankton -2024- Web Series

The title is the thesis. Plankton drifts with the current, unable to control its direction. Hae-jo, Jae-mi, and the supporting characters (including Jae-mi’s gentle but insecure fiancé, Eo Heung) are all "plankton"—drifting through life, feeling powerless against their circumstances. The show asks a profound question: If you can’t control where you drift, can you at least choose who you drift with? Cinematography & Sound Director Hong Jong-chan turns the Korean landscape into a character itself. From the misty east coast to lonely convenience stores and blooming camellia forests, every frame is painterly. The show uses color masterfully—desaturated, cold tones during moments of loneliness, bursting into warm golden hour light during rare moments of connection.
