[November 1] Scheduled private wedding ceremonyThe romantic journey of Yoon Jong Hoon and Han Eun Seo is deeply intertwined with their professional lives. The couple first crossed paths in 2018 during the production of the SBS Wednesday-Thursday mystery thriller drama Return.
- The Catalyst (Return, 2018): In the critically acclaimed and highly-rated drama, Yoon Jong Hoon played Seo Jun-hee, a fragile, drug-addicted doctor caught in a web of murder and betrayal alongside a group of elite, corrupt friends.

Choosing to keep their personal lives separate from their public personas, the couple dated quietly for several years. This low-profile approach allowed them to nurture their bond away from the intense scrutiny of the public and paparazzi, a common challenge faced by high-profile celebrity couples in South Korea.

Preparations for their autumn wedding began earlier this year, culminating in the public announcement in September.
