In this quirky and heartfelt romantic comedy, a man who feels like he doesn't belong anywhere embarks on an impulsive and chaotic journey. The series follows Hae-jo, a man who has always been a "plankton" in society—adrift and without a clear place in the world—as he sets off on an unexpected road trip. His path collides with Jo Jae-mi, a woman who has spent her life trying to control every detail, only to find her carefully planned existence unraveling. Forced together by circumstance, the two mismatched souls navigate a series of unpredictable adventures, confronting their deepest insecurities and discovering that life's most meaningful connections often come from the messiest detours. Starring Woo Do-hwan as the free-spirited Hae-jo and Lee Yoo-mi as the meticulously organized Jae-mi, the series blends laugh-out-loud comedy with poignant moments of self-discovery. With its offbeat tone and exploration of belonging, the show asks whether it is possible to find your anchor when you have spent your whole life just floating along.
