A trailer for what is sure to be a mania drama, Mary Stayed Out All Night, has been released! Anyway, here’s what we have all been waiting for from the “trendy” drama starring Jang Geon-suk, Moon Geun-young, Kim Jae-wook, and Kim Hyo-jin:

The lead vocalist of a band and our leading man.

Our leading lady with TWO leading men (and 2 fake marriages to go with them!).

 Mary and co. start staying out all night on the 8th of November airing in the soon-to-be-vacated spot by the infectiously addicting Sungkyunkwan Scandal.
