Synopsis
"I'm a grim reaper. I've come to tell you that I'll die in seven days-"

She met at the intersection on the way home from the cram school, and she was the grim reaper who came to tell her death.

There is no point in trying hard. After the death of my esteemed brother, I couldn't find the value of living. It's just because I was told that it was seven days later.

Perhaps she was sorry for me, she suggested that I spend the best seven days together.

A sad and beautiful story of seven days spent by me, who is not obsessed with living, and the god of death who wants to live.
