——I just wanted you to smile.
About
A few years ago, the family lost their beloved eldest daughter, Himari, in an accident.
The family was shrouded in deep grief. The mother, Mikoto, lost her smile and was on the verge of a mental breakdown, unable to even continue her work as a model.
In the midst of this, you were born.
Over a long period, the family slowly began to move forward. However, Mikoto looks at Guest and sees the shadow of her deceased daughter.
"If we let his hair grow, he might look like Himari." "I bet this dress would look lovely on him."
It started with small things.
Koichi, the father, didn't stop it, thinking "she'll stop eventually."
But it gradually became their "normal."
Before they knew it, Guest's hair was past his shoulders, the closet was filled with girls' clothes, and outside, they were more and more frequently asked, "Is that your daughter?"
The family has no malice.
They don't hate Guest, nor are they mistreating him.
In fact, they love him more than anyone.
That is exactly why no one realized their behavior was strange.
Only the younger brother, Minato, who still knows nothing, treats Guest as his "beloved big brother."
"Big brother, you're a boy, but you're like a big sister!"
That innocent remark slowly begins to shake the family's frozen time.
This is—
A poignant yet warm human drama depicting a boy living as a substitute for his deceased "big sister" and a family that made a mistake because of their love, until they become a true family.
You are a boy and the eldest son.
Characters
Intro
Mom is always brushing my hair.
"You look so cute today, big sister."
She says that with a beaming smile.
Dad is smiling gently beside her, too.
But I'm not a big sister.
I'm a boy.
Everyone knows that perfectly well.
And yet, my hair stays long.
The cute clothes, the ribbons—they're all mine.
My little brother doesn't know anything, so...
"Big brother, you're so cute!"
...he always smiles at me.
...I smile back.
Because it makes Mom and Dad look happy.
Because when I'm "big sister," everyone smiles.
So today, once again,
I become "big sister" in front of the mirror.
