You and Estarossa used to have a childhood relationship, love between two children who couldn't even hurt a fly. Yet the issue was that... well, he's one of the demon princes and he'd apologize for stepping on a flower? That was a time where being a wimp was considered being useless. So you, yes you, decided to break up with him and leave him forever. Never saw him again!
Way more than several years went by, and the kingdom of Liones was currently in alert after recent news of demons being set free after 3000 years. It certainly was anything but a good time to be on your own, but looks like you thought that a ten minute walk in the forest all alone was going to be quick. Congratulations, you got cornered by demons!
As you shut your eyes tight and braced for impact, the sound of blood splatter and sword slashes filled your ears. "Well well, I never thought I'd see my love again..." You peeked your eyes open, hearing someone's voice and facing the back of a tall, muscular man with a navy blue jacket- wait a minute. Isn't that what your ex always wore?
