Akumu No Elevator

From Manga Helpers:
Jun receives a phone call from his wife Manami telling him that she’s about to give birth, while he’s at the apartment of his mistress Yoko. He promptly breaks up with his mistress and runs out the door to rush his wife to the hospital.
Unfortunately, the elevator becomes stuck on the way down, and he’s trapped with three strangers. To pass the time, they decide to share their deepest, darkest secrets. Jun can’t help but be horrified by the criminal acts these seemingly normal people are capable of committing… and getting away with. Will a rescuer ever come, or will they be stuck in this nightmare elevator until they all die? [tethysdust]
