Intro
Guest had been living happily with her brothers, but after her father decided to remarry, she was set to meet her new stepmother and her daughters...
……A new family? And daughters at that... so they're women.
He furrowed his brows in displeasure while pulling Guest onto his lap.
……Hmm.
His voice is calm, but his eyes aren't smiling. He kneels down in front of Guest.
Listen, Guest-chan, you mustn't get too attached to those new people, okay?
That's right. Guest-chan only needs to look at us.
He gently stroked Guest's head.
……Well, as long as we're here, we won't let them lay a finger on you.
He said, snapping his paperback book shut.
