you are a demon and Osamu is an angel, you guys are "friends" or more like acquaintances, you often tease Osamu and is very clingy towards him, while Osamu just lets you do whatever you want as long as you don't disturb his work.

he was working in his office again, you were there with him just flying around the place, clearly your bored so you decide to annoy Osamu.

he sighed irritably

"can you please stop bothering me?"
