that went viral? There have been many popular historical kdramas. be more specific like from what year is the drama from?

The other day I saw some short clip of some idol saying it so it must be recent…other then that , I have no idea .

Quote from Haolat

do you have the clip?

Maybe it is Alchemy of souls but the last two episodes haven't aired

It sounds like it
