Hayato, who previously appeared in the thriller series "Alice in Borderland," said he felt excited to play one of the lead roles.

"The script moved me with its story of love amidst sadness and pain, and the incredible 10-year story arc crafted by director Hashizume has truly immersed me in the character," he said.

Hayato said working with Taecyeon, who is also known as a member of the K-pop boy band 2PM, "has been inspiring."

"His (Taecyeon) charm draws me in more each day," he said. "Filming in Japan, Korea, and Germany [also] gives the project a truly global feel."

"The character of Johan Hwang intrigued me, and his inner struggles and pain stayed with me long after I read the script," said Taecyeon.

"To prepare, I lost weight and underwent boxing training, and I’ve continued to train diligently during filming to portray Johan as best as I can," he added.
