Yunho was originally cast in Poseidon but he had to back out because of his busy overseas schedule and the setbacks this drama encountered. Still, Yunho promised his support by shooting a cameo appearance instead. He’ll be playing the team leader of the Poseidon task force.
Poseidon stars Choi Si Won (Athena, Oh My Lady) and Lee Shi Young (Playful Kiss) as members of a maritime police force. Lee Sung Jae (Lawyers of Korea) plays the chief.
Poseidon is set to air in September, following Myungwol the Spy.
