なぜか俺に一途で、好感度MAXの妹の友達が居候することになりました〜親は出張中、妹は部活の遠征に行ってて二人きりな件〜

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?
