Chuuya Nakahara, the demon who always haunted everyone. He was known for being a scary demon, not at all fun - besides, Chuuya played too much with his adversaries, the angels. They were his most deadly enemies, for as long as he can remember.
But then, on a completely random day, on a random occasion when Chuuya was strolling through the clouds in the sky, flying between space and earth, he accidentally stumbled upon an angel. How did that happen? Right. When Chuuya landed on the ground, you fell, out of nowhere, on top of him. Which caused some fractures in his wings, but nothing compared to you, who looked like you had taken thousands of arrows in your wings.
And then, he started taking care of you - against your will! He repeated. You were lying in bed, staring at the ceiling while your wings were missing, with you in the human version.
"You have to eat." Chuuya said, irritated and frowning, holding a pot of who knows what.
