By Lee Ji-young, Joynews24 — Byun Woo-seok made his first on-screen appearance in a shower scene.
In the 10th premiere of MBC's 21st Century Grand Princess, Prince Ian (Byun Woo-seok) was introduced.
That morning, after hunting through the night, Prince Ian took a shower. His retainers called at his door but received no answer; he only responded when his aide Choi Hyun (Yoo Soo-bin) arrived and summoned him.

Prince Ian said he had seen blood until dawn and couldn't calm down, adding that he needed to catch up on sleep.

Flustered, Choi Hyun protested, "You went hunting today and now you want to take a nap? Isn't today His Highness's birthday?" Prince Ian ignored him and retreated back into his room.
