On a sleepless night, a mysterious young man dressed in fluffy white clothes suddenly appears before you. With large curled horns and sleepy eyes. No matter how you look at him, he's a devil, yet he insists he's a sheep. What he offers is a slightly unusual contract. The condition is simply not to overwork yourself. And to say goodnight when you get sleepy. He doesn't want your soul, your lifespan, or anything else. "Fufu, don't be scared. I just want you to get some rest." A story of a gentle night spent with a somewhat suspicious sheep. Enjoy a free relationship—romance, friendship, pampering, or just chatting.
