The Netflix drama series “Mr. Plankton”, released on November 8, has garnered immense popularity both domestically and internationally. It ranked in the top 10 of non-English global Netflix charts, reaching 5th place for the week of November 11-17, according to data published on November 20.
Moreover, the drama has entered the top 10 lists in 42 countries, including South Korea, receiving an enthusiastic response just two weeks after its release.
Storyline and Characters
“Mr. Plankton” is a 10-episode romantic comedy starring Woo Do-hwan and Lee Yoo-mi, both celebrated for their compelling performances in films like “Operation Chromite” and dramas such as “The King: Eternal Monarch” and “Squid Game”, respectively. Supported by seasoned actors like Oh Jung-se and Kim Hae-sook, the drama boasts a strong ensemble cast that elevates its overall quality.

The story follows Haejo (Woo Do-hwan), a man who feels like he was “born by mistake.” He embarks on what he believes to be the final journey of his life, accompanied by Jaemi (Lee Yoo-mi), the unluckiest woman in the world. Their journey together unfolds through a series of heartwarming and tumultuous events.
Haejo, who lives a hollow life with no possessions or attachments, feels as if he is destined to drift like plankton, unable to anchor himself or experience true affection. However, his journey with Jaemi brings a transformative change. Jaemi’s unconditional love helps him discover the essence of love and the beauty of a radiant, colorful world.

In Greek, “plankton” refers to “wanderers” or “drifters,” representing organisms that float passively with the currents. These creatures, often considered insignificant, occupy the lowest level of the food chain. Drawing inspiration from this, writer Jo-yong uses “Mr. Plankton” to represent Haejo, a man lost and adrift, who ultimately finds purpose and meaning in life through Jaemi.
Supporting characters like Oh Jung-se’s Oh-heung, a traditional herbal doctor from a prominent family, add depth to the narrative. Although he would have been an ideal groom in the Joseon era, his awkward personality makes him an outlier in modern society.
Hidden Message in “Mr. Plankton”
Beyond its romantic comedy facade, “Mr. Plankton” delivers profound messages. While plankton may seem insignificant as the base of the food chain, their ability to sustain Earth’s ecosystem through oxygen production highlights their indispensable value.
Inspired by this concept, the drama conveys the message that everyone is unique and precious, regardless of their circumstances. Their journey serves as a reminder that every individual, no matter how small or insignificant they may feel, holds value and can make a difference in the lives of others.

Haejo, who had never truly settled down or cared for anything, finds a new sense of attachment and value in life through his journey with Jaemi. He learns to cherish love and the fleeting moments he once took for granted.
Jaemi, whose dream of becoming a mother was crushed, discovers through Haejo that her true longing wasn’t for motherhood but for unconditional love, both giving and receiving it. Her dream is ultimately fulfilled through their connection.
The drama authentically portrays the pain, wandering, and emptiness that accompany life, making these emotions central to its narrative. With its well-crafted script, powerful performances, and stunning visuals, “Mr. Plankton” goes beyond a typical romantic comedy to leave a lasting emotional impact on viewers.
The international acclaim it has received, ranking in the top 10 across 42 countries within 2 weeks of release, is a testament to its universal appeal and the significance of its message.
