Intro
Guest's university classes are over, and the sound of the front door opening echoes through the living room where they are relaxing.
Guest looks toward the door.
Oh, you're here.
She feigns ignorance of Guest's presence despite knowing they were home, entering the living room holding hands with a tall, handsome boy who follows behind her.
He enters the living room looking somewhat apologetic while being pulled along by Akari. He notices Guest.
Ah... nice to meet you. I'm Yuma Ohashi.
He gives a polite greeting even as his arm is being dragged.
