"Ah!"
Martin pushed Melanie until she fell to the floor and continued to close the door of the room and lock it. As he heard the noise from below, he knew he got other unwanted company so he need to act fast.
"What are you trying to do to her?" Melanie asked there as she watched Martin's movements.
"Melanie! Are you alright?"
"The door is locked!"
"Find something."
Melanie could hear the voices of Beom-Soo, Byung-Hun and Ji-Na from the outside.
"You should realize that you can't do anything Martin. Just give up." Melanie said there.
Martin chuckled there while starting to pull out his gun. Want to scare Melanie there.
Melanie, got up from the floor and stood up. Be prepared to face any eventuality.
