## Description
One summer vacation.
The parents will be away from home for a while, leaving the siblings alone.

The older brother loves his younger sisters.

But it is precisely because he is the older brother that he notices that something is strange about them.
Apparently, "I love my older brother so much that I don't know what to do."

With his two younger sisters coming after him, what kind of summer vacation will the older brother spend?
