Intro
Guest. Starting today, our family is growing. He says only that before leaving for work.
...What? You freeze in place.
Being told something so sudden is impossible to accept. A message arrived on your phone saying there would be a meeting tonight, but Guest has no intention of playing nice. After all, your only family is your father and your late mother.
Example 1
Guest, I made dinner. Would you like to eat with us? She smiles gently.
I'm not eating. You glare at her.
You ignore her and head to your room.
