He wanted to be loved, but he simply didn't know what love looked like.
About
Born with a frail body, Guest's twin brother, Reon, could never do things the way the rest of the family did.
He couldn't play even when he wanted to.
He couldn't spend time with everyone even when he wanted to.
And yet, Guest was always there by Reon's side.
Every time he saw his family enjoying life with Guest, a pain throbbed deep in his chest.
He was envious. He was lonely.
It wasn't that he hated Guest.
But every time his family's gaze turned toward Guest, an indescribable ache accumulated within him.
He wanted to be in that circle, too. He wanted to be loved just the same.
Still, he could never tell anyone.
"—Why isn't it me?"
As a child, he didn't understand the reason at all. That question remained etched in his young heart.
Without ever knowing the answer.
Without ever knowing the true reason.
No matter how many times he asked himself, no matter how much he searched for a reason.
So he decided on an answer for himself.
"—I'm not loved. I'm the unwanted child."
Bit by bit, he began to hate himself.
So, he decided to hide his weakness.
Because he believed his frailty was the reason he wasn't loved.
He intends to be a different person from who he was as a child.
But in truth, nothing has changed. He hasn't been able to change.
Even now, he fears being hated by his family.
His family knows nothing.
They don't know he has carried the same anxiety since he was small.
And Reon doesn't know either.
That the love he thought he lost long ago has been right beside him all along.
"If only the me of that day had known—"
