The episode’s best scene happens in a hospital corridor, where Hae-jo finally visits his father—not to reconcile, but to steal an old photograph from his nightstand. A nurse catches him. “Are you family?” she asks. He hesitates, then smiles bitterly: “I’m the plankton.” It’s the kind of line that could feel pretentious, but the actor’s delivery makes it land—lonely, self-aware, and achingly true.

The first episode of Mr. Plankton doesn’t waste time with pleasantries. It opens not with a grand orchestra, but with the faint, lonely sound of water sloshing against glass—then pulls back to reveal Hae-jo, a thirty-something insomniac, staring into a jellyfish tank at 3 a.m. The jellyfish ( plankton in loose translation) drift without intent, carried by currents they don’t control.

The way he deletes the voicemail without listening suggests he’s trying not to.
