10 Years Younger, Kim Jae Won's Portrait as Kim Go Eun's 'Last Love' in YUMI'S CELLS 3

The YUMI’S CELLS drama is adapted from a famous webtoon of the same name. The story follows the life of Yumi (played by Kim Go Eun), an ordinary office worker whose story is viewed from the perspective of the cells in her brain. Each cell represents emotions and thoughts that influence Yumi's daily decisions and actions.

The first and second seasons were a huge success and received a lot of love from audiences in various countries. In the third season, Yumi is no longer an ordinary office worker. After going through many struggles, she is now known as a successful romance novel writer.

However, even though her career is soaring, matters of the heart remain the biggest challenge in her life. The village of cells in her mind feels empty and flat until a new figure named Soon Rok appears.

The character Soon Rok will be played by Kim Jae Won. He is the new PD in the editorial department of Julie Publishing. Although his appearance is gentle, he is known for his honest and straightforward demeanor.

Initially appearing cold and only influenced by 'rational cells', Soon Rok actually holds unexpected charm. His calm life begins to change when he is assigned to work with Yumi, whose emotional cells are often chaotic.

"It feels wonderful to be part of a project that is loved by so many people. I will do my best to portray the character Soon Rok well. Please support me," said Kim Jae Won in response to his role as reported by Soompi.

Yumi’s Cells Season 3 is scheduled to premiere in the first half of 2026 on the TVING platform. Who is already looking forward to it?
