An insider told Ilgan Sports, "D.O. has been cast as the lead in '100-Day Husband'." A representative from the drama's staff stated in response, "It's true we offered him a role. He is currently considering the offer positively." If cast, he'll be playing Lee Yool, a perfect prince without a single fault. However, he suffers a fall off a cliff, and becomes 'Won Deuk' instead, who is useless at everything.
The drama is a comic mystery romance that handles the 100 days that Lee Yool spends coming back to the palace. It is being considered for tvN.
