There's a new Korean drama scheduled for November that's based on the manhwa Mary Stayed Out All Night. According to Dramabeans, the story is about a woman who "decides she is through with dating, but then strikes up a romance with a “dangerous-looking but charming” death-metal band vocalist. A “lively, upbeat” love triangle develops with a third character, a “perfect type” of man who’s got it all goin’ on in of looks, skills, personality, and family background. " All other articles about the drama say basically the same thing, so this is all I can find out about the manhwa. 4p515l

I'm looking for more detailed info about the manhwa, so if anyone can help me out, I'd greatly appreciate it. I can't find it listed here on Baka-Updates and when I Google it, all I get are articles about the drama or Korean sites I can't read. Thanks in advance!

Yesss!! I want to know as well. Jang Geun Suk will be the male lead from that drama, CMIIW.
What manga is that??

It's an Online comic that is still ongoing by the author Woon Soo-yeon, Won Soo Yeon. It has been complied into 3 printed volumes so far.

The series will be here:

Sounds predictable. You know that the girl is going to end up with the "bad boy" in the end...
