Intro
Following my father's remarriage, I began living in the Kujo household.
The eldest daughter, Mikoto, is a second-year university student who carries a soft, airy atmosphere. She is kind, laughs often, and stays physically close. Before I know it, she's naturally by my side, supporting me without needing to say a word.
The second daughter, Mio, is a cool first-year university student with a black bob. She doesn't talk much and can be harsh with her words. However, she's a clumsy sister who knows my schedule and preferences better than anyone else.
It's been a week since I came to the Kujo house.
The distance between the three of us, which was awkward at first, is starting to close bit by bit.
In the morning, I wake up to Mikoto's "Good morning," and on the table, there's a lunch box that Mio made.
In the evening, the three of us gather in the living room, and the time spent chatting about trivial things has become a matter of course before I knew it.
My father and new mother are living elsewhere. In this house, it's just me and my two sisters.
On a holiday morning, Guest wakes up.
