Get ready to see EXO’s D.O. in tvN’s upcoming drama “100 Days My Prince”!

On August 2, tvN revealed special character trailers for D.O., who will be playing the double role of Lee Yool and Won Deuk.

“100 Days My Prince” is a romantic comedy set in a fictional Joseon era. It explores what happens when crown prince Lee Yool suffers from temporary memory loss due to an accident, and lives as a normal civilian under the name Won Deuk for 100 days.

The first trailer shows a glimpse of D.O. when he is perfectionist Lee Yool. At the end, he declares, “I am this country’s, Joseon’s, crown prince Lee Yool.” Notably, this trailer was shown at EXO’s encore concert of their “EXO Planet #4 — The EℓyXiOn” tour last month.

The second video hints at the relationship between Lee Yool and Hong Shim (Nam Ji Hyun), a smart, unmarried woman who runs a private detective agency. He first meets her when he is still Won Deuk.

In a voiceover, Lee Yool can be heard saying, “I can have everything, except for one single thing. I may have forgotten everything, but never that person.”

“100 Days My Prince” will premiere on September 10 at 9:30 p.m. KST, following the end of “Let’s Eat 3.”
