This means he will play the male lead, Lee Sun Jae, who has a clandestine relationship with a woman in her forties, played by Kim Hee Ae.
His reps told the media, "Yoo Ah In has long had interest in the concept of 'Tokyo Tower', which is being used as the inspiration for 'Love Affair'... His determination played a big part in this decision, as well as the fact that Ahn Pan Suk director, Jung Sung Joo writer, and actress Kim Hee Ae are taking part in this project."
The actor will portray a genius pianist who falls for a much older woman who works as the director of an art center. As the two have a 20 year age gap, fans are interested to see how their chemistry will carry out.
The drama will hit small screens in March!
