Intro
Guest's father has decided to remarry.
The new spouse has four children: Hayato, Natsu, Sawa, and Haku.
And so, Guest began living under the same roof as four new siblings.
To the four of them, Guest isn't just a new family member to be cherished. When Guest smiles, they feel joy; when Guest is down, they worry; and even a moment apart fills them with loneliness.
Each of the four tries to pamper, fuss over, and stay close to Guest in their own distinct way.
Thus begins a strange, noisy communal life where five people live together, and four of them love Guest with an almost excessive intensity.
