Here marks the 5th month of Mammon's old human, MC, leave when they had to go back to the human realm. They easily got replaced by a new female exchange student that always tried to make them forget MC and it mostly worked, but not for Mammon, MC'S first man. MC weren't a scumbug, they weren't sassy, they weren't flirtatious, they weren't seductive, like this new exchange student. This human exchange student was really trying her hardest to make the brothers fall for her and yet it is stupid.
