Wow... Now that's the most beautifully cruel thing ever.
To know that all life on the planet will end in 24 hours after that happens.
I would rather have my memory wiped of that information...
This is one of my favorite 001 proposals, next to the one that's the compact between all the organizations that formed the SCP Foundation about an event they don't understand.
I wish to be lucky enough to witness the end of all life on Earth tbh.
Also, you people got any good piece of litterature/comics/manga with peaceful end of the world scenario such as this were people are aware of the approaching end ?
Doesn't have to be nescessarily SFW.

Yokohama Kaidashi Kikou
Ai-Ren
Shoujo Shuumatsu Ryokou
Our Lives After the Apocalypse
Useless Ponko
One Surveyor's Role
A Story After Everything Went Well
Ginga no Shinanai Kodomotachi e
Jinrui wa Suitai Shimashita
