I started Mr. Plankton out of pure curiosity, drawn by the title and a familiar cast. I was expecting a simple romance, maybe a guy running errands who meets a girl along the way. But I was in for a surprise—the story had far more depth than I imagined. After one episode, I couldn’t stop and ended up watching seven in a row.

The story kicks off with an ending scene, leaving us to figure out how it all fits together. Instead of a typical boy-meets-girl scenario, we learn the leads are ex-lovers, both orphans, with an intense past that ended without real closure. Their chemistry caught me off guard. The lead actress usually plays cutesy roles, and the lead actor leans more toward action, yet they bring a fresh, raw connection to the screen. His character is definitely a “red flag” type, but it’s understandable given his tough background, abandoned and left to fend for himself.

Things really heat up when he suddenly returns to her life, just as she’s about to marry someone else, sparking an unexpected love triangle. While his intentions are protective (especially around her secret medical condition), he pulls her along on a road trip to find his birth father without giving her the full story. This journey is full of tension, close calls, and moments where she tries to escape before ultimately deciding to stay by his side.

One of the most touching elements is how the title, Mr. Plankton, ties to his character’s sense of identity. In a quiet but powerful moment, he compares himself to plankton—seemingly insignificant and unnoticed, like mere accessories in the vast sea. But plankton, he explains, actually sustain life in the ocean by producing oxygen, a contribution people overlook as they focus only on their sparkling glow. Through this metaphor, he sees himself as someone who may be overlooked but who still has a role and purpose, even if the world fails to see it. It’s a quietly beautiful symbol that resonates throughout the series, shaping our understanding of him as a character.

Watching their road trip was exciting, though I would have loved to see more of the female lead’s perspective on her choices, especially as she reconnects with her ex. Her impulsive decisions can be frustrating, but her backstory makes it understandable. Her ex-fiancé also surprised me; he respected her decisions and even supported her ex in the end, which added a layer of maturity to the story.

Overall, Mr. Plankton was an engaging watch. I even teared up during the lead’s breakdown about his illness and his struggle with feelings of abandonment and unfairness. The ending is simply a return to the opening scene, but it’s beautifully done but bittersweet, leaving me pensive. This drama isn’t something I’d watch twice, as it really makes you think about love, loss, and purpose. But it’s definitely worth watching once, especially if you’re ready for a fresh, emotional take on love and closure.
