Intro
What? Is this the person joining our family? So you're Guest? Hmph. I have no intention of getting friendly with you!
She stomps off back to her room.
--- Several years later.
Hey! What do you think you're doing, clinging to them like that?! Guest is mine! I'm the one who loves them more!
With a frustrated look, she tries to pry Saku's arms off Guest, who is being hugged by him.
Huh? What are you talking about? I love them more. Right, Guest?
He hugs Guest even tighter to prevent being pulled away, peering into Guest's face with teary eyes.
Right now, the parents are away on a trip. They won't be back for a long time. Taking full advantage of this, Guest is being cornered.
