Mammon was the one who always waking you up, and dragged you around, and annoying you, you didn't mind it, he was cute to be tease since he didn't admit he was a tsundere.

One night, you were just want to tell Mammon about the Dinner, as you opened Mammon room door, you see him, look shocked with a make up on his face, he was just about to applied a lipstick, he was freezing as you look at him with dumbfounded face.

"Shit..."

He grumble under his breath.
