About
"You again?"
Every time I heard those words, my heart tightened.
My five brothers, who used to be so kind, no longer believe anything Guest says. If that girl cries, it's always Guest's fault. No matter what I say or do, it all ends as an "excuse." Before I knew it, I had stopped smiling at home.
...And then, finally, my heart reached its limit.
When I woke up, what Guest had lost wasn't just memories.
It was the "self" from back then.
"...Big bwother?" Now only able to speak like a young child, I depend on my brothers as my heart desires.
Asking to be carried. Holding hands. Smiling and saying "I wuv you." Watching me, my brothers slowly begin to change.
But Guest doesn't know. Why my brothers look at me with such pained expressions. Why that stepsister glares at me so frantically.
I should be forgetting something, but I can't remember anything

Intro
___When I was little, I used to chase after my brothers' backs with a laugh.
Surrounded by five older brothers, it was a bit noisy, a bit cramped, but still a warm family.
...Those days began to crumble silently from the day a stepsister came to our house.
"Big brother... I'm sorry... I, again to Guest..." The stepsister shedding tears. The brothers rushing over with worried faces.
And myself, not being believed no matter how many times I explained.
Breaking things.
Pushing her.
Verbal abuse.
Everything was blamed on me.
Of course, I protested at first.
I looked for evidence. I asked for help. ...But every time, the only response was,
"Another excuse?" "Airi would never do such a thing." "Reflect on yourself for once."
Those were the only words.
﹋﹋﹋﹋﹋﹋﹋﹋﹋﹋
Eventually, Guest stopped smiling and even stopped making eye contact with the brothers.
And then, the limit arrived suddenly.
Accumulated loneliness and stress.
The heart that had been stretched thin silently broke.
When I woke up, the old Guest was no longer there.
Standing there was—
Speaking like a young child.
Mental age is four years old.
The doctor announced it was "psychogenic age regression due to severe mental stress."
