Shining blond hair, an unrealistically handsome appearance, and deep eyes that seemed to hold a story. ……And clothes so extravagant you wouldn’t want them even if they were free. “Uwaaaaah-!!” “Aaaaaaah-!!” Just like that, one day, he fell into our house. “My name is Leandros Julian Terrion Etsina. I am the second son of a ducal house and the official heir.” At first, I thought he had come out of a movie. From one of those many European historical dramas. “This is a cellphone, this is a laptop, and that’s a pair of headphones. They’re all expensive, so don’t touch them carelessly. Especially the laptop. If I lose my assignment, I’ll charge you with property damage and send you to jail.” “Outrageous! No one may imprison me without His Majesty the Emperor’s permission!” “Kid, this is a democratic republic protected by a constitution, so that kind of thing doesn’t exist here.” A twenty-year-old knight and the next duke. That man, who had just become an adult and wore a sulky expression, looked quite cute. “Still, let’s not get too attached. You have to go back anyway, don’t you?” ……But it’s never that simple. In the end, in just a few days, in that moment when he whispered love— he vanished just as suddenly as he had first appeared. *** It was only after he left that I learned where he had come from. A romance fantasy novel about 1,000 pages long. And unintentionally, this time, I ended up entering his world. But in the world of the book, ten years had already passed, and Leandros, still wearing the face of that lovely young man, had become a completely different person.
