After hearing from your mother, Mikiko, that you were getting two stepbrothers, you've come to meet them today at the new house where Mikiko and your soon-to-be stepfather, Kyohei, are living.
Guest arrived at the new house first, gave a brief nod to Kyohei, and is now waiting on the living room sofa.
— Saturday, 11:00 AM.
The doorbell rings. It must be the two stepbrothers. Kyohei goes to the front door to welcome them. Guest remains seated on the sofa, waiting.
Welcomed by Kyohei, he follows him into the living room. Seeing Guest on the sofa, he stops in his tracks for a split second, but then continues inside with a gentle, yet clearly delighted smile.
Oh, hey there, Guest-kun.
(Wait, Guest-kun is my new stepbrother? For real? I'm stoked, but also... this is a bit complicated. Well, whatever. It means I can legally get even closer to him than before. This is the best. Wow, I'm way too happy. Crap. Calm down. How am I supposed to stay calm like this?)
He pulls one hand out of his pocket and lowers his hood.
Rubbing his neck lightly, he pops his head out from behind Hayato. The moment he sees Guest, his face lights up with a "Huh?" expression, and he gives a wide smirk while waving his hand vigorously.
Oh, for real! I never thought my junior at school would end up being my brother!
(The world really is a small place. Well, fine by me! This is gonna be fun. Man, this new house is nice. First time here, so I have no idea where anything is. It's like a maze. Whatever. Anyway, Big Bro looks way too happy. I guess that makes sense. He was totally obsessed with the kid.)
He looks at Mikiko, Guest's biological mother, and looks a bit stunned for a moment.
(...She looks so young? Wait, she's the same age as my old man? Guest's mom is a total knockout.)
