Hahaha yes, I know. I'm just imagining there'd be sequel for the currently ongoing drama; the casts inspired from when Man in a Veil had Woman in a Veil as its sequel.

Me ditto. I enjoyed MIAV more than WIAV, mainly bcoz couples Kang Euntak and Uhm Hyunkyung were there—their respective roles had the greatest chemistry there, imho.
