Channel A’s upcoming drama “Check in Hanyang” has unveiled a fun new teaser!

Set in the Joseon Dynasty, “Check in Hanyang” is a historical romance drama that depicts the growth and love stories of youths who join as “interns” at Yongcheonlu, the largest inn in Joseon.

Bae In Hyuk plays Lee Eun, a prince who joins Yongcheonlu under the alias Lee Eun Ho while hiding his true identity. Kim Ji Eun stars as Hong Deok Soo, a woman living as a man for an unknown reason. Jung Gun Joo plays Cheon Jun Hwa, heir to Yongcheonlu, while Jaechan plays Go Soo Ra, who hails from a once-prominent family now fallen into ruin.

The new teaser begins with the introduction of Yongcheonlu: the grandest inn in Joseon located opposite the King’s royal palace. The narration remarks, “At Yongcheonlu, the guest is king.” Lee Eun Ho quickly bursts out in protest, shouting, “How dare you call them kings! Do you all have a death wish?!”

As the confused interns look on, Hong Deok Soo mutters, “Better not get involved with him…” However, the quartet soon earns a reputation for causing trouble at the inn. Branded as the “Gang of Four Buts” for their constant “But—” during punishments, they develop a camaraderie.

Nearing the end of the teaser, Cheon Jun Hwa remarks, “Now that we’re on the same boat, shall we face this storm together too?” hinting at the beginning of their chaotic but endearing friendship.

“Check in Hanyang” will premiere on December 21 at 7:50 p.m. KST.
