Onward

A single ripple can change the entire current of a life. Woo Seungwon is a gifted swimming prodigy whose presence carries the boundless depth and quiet intensity of the open ocean. His path unexpectedly intersects with Doh Si-on, a former chart-topping singer who has long since stepped away from the spotlight. Now navigating the corporate world as a businessman, Si-on fights daily just to keep his head above water. Despite his relentless efforts to rebuild his future, the heavy burdens of his past and present threaten to pull him under, leaving him feeling trapped in an exhausting struggle for survival. Drawn to the young swimmer's remarkable nature, Si-on approaches Seungwon with an unconventional proposition. He offers the athlete a position as his personal housekeeper, providing a chance to earn supplementary income outside the pool. However, this arrangement comes with an unspoken layer, hinting at additional, more intimate expectations behind closed doors. As their lives begin to intertwine through this complicated agreement, both men find themselves navigating uncharted waters that could either anchor them or set them entirely free.
