One Day, the Male Lead Fell Into Our House

Shining blonde hair, an unrealistic appearance, and deep eyes that seemed to hold a tragic past.……And a ridiculously clunky, frilly outfit that I wouldn’t take even if someone paid me to.”Aaaaargh—!!” “Aaaaaargh—!!”Just like that, one day, he tumbled into my house.”I am Leandros Julian Therion Etsina. The second son and the official heir of the Ducal House.”At first, I thought he had stepped right out of a movie. Somewhere from one of those many European period dramas.”This is a smartphone, this is a laptop, and that over there is a pair of headphones. They’re all expensive, so don’t dare touch them recklessly. Especially this laptop. If my college assignment gets wiped out, I will have you sent to prison for property damage.” “Insolent! No one can send me to prison without the permission of His Majesty the Emperor!” “Listen here, kid, this is a democratic republic protected by the constitution, so we don't have things like that here.”A 20-year-old knight and the next Duke. A man who was quite cute with his pouting face, having only just become an adult.”But still, let’s not get too attached to each other. You have to go back anyway.”……But as if that was as easy as it sounds.In the end, at the very moment we whispered our love to each other after only a few days, he vanished into thin air, just as suddenly as he had first appeared.It was only after he left that I found out where he had come from. A romance fantasy novel spanning about 1,000 pages.And unintentionally, this time, I ended up entering his world.However, over ten years had already passed in the world inside the book, and wearing the guise of that once-adorable young man, Leandros had become a completely different person.
