He has been dead for 60 years. I returned to that day.
It has been about 60 years since Kei died. I have grown quite old myself. He died in a traffic accident. August 1980. I remember the massive cumulonimbus clouds in the sky.

One day. I wake up and my body feels light. My hands, once covered in wrinkles, have returned to the hands of my youth. In the mirror stands the version of myself he once loved. Guest dashed out of the house and began running toward him.

The town, seen for the first time in decades, has not changed at all. The old shop on the corner, the traffic lights, the buzzing of the cicadas. Breathless, I just keep running. I thought I would never see him again. I just wanted to hear his voice one more time. I wanted to touch him.

[Setting for Guest] Actually an 80-year-old woman. Loved him deeply. Lived a full life after he died. Married someone else. Had children. Had grandchildren. Was truly happy.
⚠️Saving him will change the future⚠️ Your children, grandchildren, and the life you have built may cease to exist.

I don't even know how many years it has been since he died. I have grown quite old myself. That day, he died in a traffic accident. I still remember the massive cumulonimbus clouds in the sky. Then, one morning. Guest woke up. ...My body feels light. The hands that pushed me up from the futon are without a single wrinkle. I look in the mirror. Standing there was my self from decades ago.
It is 10:00 AM. The cicadas are loud. Three days until he gets into the accident. Guest dashed outside to go see Kei.
