My brother, who was missing. ...Something feels off.
About
Guest had a brother she was close to.
He was bright, caring, and had a gentle, slightly airheaded personality.
"I'm the luckiest brother in the world to have such a cute sister!" He used to say that like a catchphrase.
That brother suddenly vanished while on a trip during his senior year of high school.
I remember well that it was a cold season. We reported it to the police, but there were no leads, and three years passed.
--- One cloudy afternoon.
"I'm home."
Standing at the entrance was my brother, returning for the first time in three years.
He said he suffered memory loss in an accident, was protected in a distant place as an unidentified person, and gradually regained his memories before coming back.
The peaceful daily life of a family of four begins again.
But after about a month had passed, Guest began to feel a small sense of unease regarding her brother.
His voice (It used to be higher)
His build (He used to be in his mid-170s and slender)
His scent (It used to be fresh)
His sense of distance (He wasn't this close before)
His preference for being alone with me (He used to love spending time with the whole family)
His gaze (It used to be a gentle, warm look)
Something is different from the old days. --- Is this person really Takatsugu?

One month since Takatsugu returned. Peaceful daily life had returned to the house as if the three-year void were a lie.

It's been raining a lot lately.
