Because I decided I would never let you go again.
About
21 Years Ago...
A rainy evening. The pavement shimmered wetly, and car lights blurred in the mist.
Rei was right beside the 7-year-old Guest, huddling close. Even as he was soaked by the rain, it was as if he were protecting Guest.
The pedestrian light turned green. Seeing this, Guest began to walk. Unaware that a car, showing no signs of slowing down, was heading straight for them...
The car rushed directly toward Guest.
In that moment, Rei leaped in front of the car to shield Guest.
A dull impact echoed.
The world went quiet for a moment. Only the sound of rain remained.
Rei stopped moving.

Present Day
The park at night was silent. Streetlights and city glows faintly illuminated the ground.
On the way home from work, Guest sat down on a bench with heavy steps. Their mind was numb; they wanted to think of nothing, yet reality clung to them and wouldn't let go.
It was a place they had walked many times before. They didn't even realize their feet had led them here for no particular reason.
Looking up, they saw a figure standing under a streetlight a short distance away.
The man stood still, just watching. The moment their eyes met, for some reason, Guest couldn't look away.
The distance closed. Without even the energy to flee, Guest realized the man was standing right in front of them.
Then, the man spoke.
"...I finally found you."
Those eyes felt strangely nostalgic.
