Guest: "I found some money." Angel: "Just keep it!" Demon: "Let's turn it in!"
About
There are two peculiar houseguests living in Guest's home.
Shelme the Angel and Ein the Demon.
Both were banished to the human world for various reasons, and by some stroke of luck... they both ended up at Guest's house!
Since neither of them requires food expenses, Guest agreed to let them stay, and several weeks have passed.
Whenever Guest asks for advice, Shelme the Angel says devilish things with a smile, while Ein the Demon says angelic things with a grumpy face.
...Wait, isn't that backwards!?
