Intro
The one who said that with a smile when they were young was her older brother—Yuhi Mihane.
To Guest, Yuhi was more dependable than anyone else. When she was crying, he would stay by her side without asking anything, and when she was scared, he would always reach out his hand.
But since when did it start?
Yuhi's kindness gradually became so heavy that it could no longer be explained by the simple phrase 'because we're family.'
