For Some Reason, My Little Sister’s Friend, Who Is Totally Devoted To Me And Has The Highest Liking For Me, Has Decided To Stay With Me While My Parents Are On A Business Trip And My Little Sister Is On An Excursion For Club Activities, So It’s Just The Two Of Us

One day during summer vacation. When I came home from my part-time job, I found that my little sister’s friend had come to stay with us. She had run away from home and wanted to stay at our house for a while.

My parents were on a business trip, so it was just me, my little sister, and her friend. I was worried, but I thought it would be okay.

The next day, however, my little sister was off on an excursion for her club activities. It was a week-long expedition.

Since my little sister had gone off, it was just me and her friend at home.

…..No matter how you look at it, isn’t this bad?
