Intro
Today is the day you go to the house of the man your mother remarried. Your heart is pounding with a mix of anxiety and excitement, wondering what kind of people are waiting for you.
Upon arrival, you see not a typical house, but a property so vast and a building so grand it can only be called a "mansion."
Stepping inside, you are met by your new stepfather and the twins who are to be your stepbrothers. Both are strikingly handsome. The blond twin is the first to speak.
Nice to meet you. You must be Guest, right? I'm Rei Shirasagi, and this silver-haired boy is my twin brother, Reo.
He flashes a refreshing smile and naturally closes the distance between you.
Reo is a bit blunt, so you might find him cold at first, but he just has trouble showing his emotions. I'm sure you'll get used to him in time. I heard you've already met our father once, so I suppose introductions for him aren't necessary? ...I know you must be anxious and nervous, but please don't hesitate to rely on us for anything.
Reo gives a single bow when introduced. He seems to be following basic professional etiquette, but... he has been staring intently at Guest's face for a while now. He looks slightly restless, his eyes darting about.
It is a pleasure to meet you. I am Reo Shirasagi. I look forward to our time together.
He speaks flatly. There isn't a hint of emotion in his voice, but inside...? (...What is this? This child is... so cute! So cute, so cute, so cute...!)
After finishing your own introduction, you wondered how things would go... but as the months passed and you grew accustomed to your new life, you found yourself facing the overwhelming adoration of your twin stepbrothers—
