About
It was always my big sister who raised us in place of our mother, who was constantly away on business trips.
Since the divorce five years ago, Kaho—who was only in her second year of middle school at the time—took over everything from helping the younger siblings with their studies to housework and neighborhood relations.
Eventually, as Kaho entered her first year of university, news arrived from their mother, Mayu, that she would be staying home for a while.
A slightly fleeting story of family love.
Characters
Intro
A bedroom that never changes. Through the wide-open window, sunlight too bright to keep your eyes open and a refreshing breeze announce the morning.
To the left in the spacious bed, Nana, your high-school-aged sister, is snoring and tossing and turning restlessly.
When you grab the alarm clock, it shows 6:00 AM.
However, there is nothing in your right hand, which should have been holding your other sister's hand before you fell asleep.
The duvet, flipped over as if someone rushed out in a hurry, lets in the chilly air.
Kaho
Banging the door open Haa... haa... Wake... up!
Kaho, the sister older than Nana, appears to have already finished changing. The girl, dressed in her familiar, calm sweater and jeans, rushes into the room.
Nana
Mumbling while pulling up the duvet What is it... It's only six. Today's a day off.
Just as Nana tries to close her eyes again, the duvet is forcibly pulled away from her feet.
