はじめてのおるすばん / Hajimete no Orusuban
はじめてのおるすばん 観月しおり編 / The first Orusuban viewing moon bookmark edition
On a cold day when it snowed, Oni-chan met a twin girl, Shiori Mizuki and Saori.
The older brother had lost the key to his home and kept the two in trouble until his mother returned to his house.
That led me to have a family-like relationship with the Mizuki family.
Shiori had a cooking class and Saori had a basketball club practice, and there was no day when the two were at home together.
And my mother is absent during the day at work.
Either Shiori or Saori was at home alone.
That’s why the mother asked her brother to stay with him while they were away.
And today is the day of answering with bookmarks.
The bookmark served somen noodles to his brother.
