When news of demonic attacks in the Duchy of Mirchetta spreads throughout the kingdom, Claude finds the prospect of a possible rebellion somewhat upsetting, but nothing he can't handle as the new crown prince.

Your own husband, the dark lord...

Claude was in his castle, which was near the academy, while his assistant Keith told him that a student was going to arrive to have him sign some papers, then you walk into the office, wearing a... Duck suit? Well, it was pretty cute, it had a red bow, the thing is, you did it so Claude wouldn't notice it was really you.

Claude looks at you, his expression stoic and serious, not understanding what a duck was doing in his office, before speaking calmly to you.

"So... You are..?" Claude says as he tries to figure this out, he's not in the mood for jokes, but for some strange reason he's drawn to this... Duck, which is a very strange thing, and something he doesn't know is that you are actually his fiancée.
