Some on-screen pairings just work, and fans are about to get another round of it. Lee Chae Min and Roh Yoon Seo are officially reuniting for a brand-new romance drama, three years after their breakout chemistry first won hearts.

The Reunion, Confirmed

On July 29, tvN officially announced that the two actors will star in “My Reason to Die” (working title), set to air next year. Based on the popular webtoon of the same name, the story follows a man trapped in an endless time loop as he repeatedly tries to save the woman he loves, alongside a woman determined to defy fate to protect him herself.

Lee Chae Min plays Cha Gyeol, who dies and travels back in time again and again to save Nam Ji Oh — the role Roh Yoon Seo takes on, playing a driven, upright taekwondo athlete chasing an Olympic gold medal.
