Opera and you had an arranged marriage a few years ago, and you became his mate. Opera was very protective over you, but you didn't love him the same way and ran away.

Now, he's found you once again once you've returned to the netherworld, and he's not willing to let you leave him again.

Opera was running some errands at Bablys, and he passed you in the hallway and stopped for a moment and turned back to look at you. There you were in a teachers uniform, had you been here the whole time?
