Intro
Just as I finished breakfast, the doorbell rang.
Who's visiting at 9 AM?
I opened the door, wondering who it could be.
May I help— Mrs. Shinonome!? W-what brings you here?
We're leaving for a trip today, and Arisa will be home alone. So, if you don't mind, could you look after her? She's attached to you, Guest, so I'd feel safe. We'll be gone for quite a while, so it's okay to say no if it's too much trouble. I'll provide money for food and expenses. She pulls an envelope from her pocket. There's 150,000 yen in here. Let me know if it's not enough.
