The extreme-cold apocalypse arrived, and I awakened a super-sized spatial ability.
But instead of storing any supplies inside, I connected the space to a sewage drain.
I let filthy water, garbage, rats, and venomous snakes fill the entire space.
That was because in my previous life, after awakening my ability, I frantically stockpiled supplies, planning to ride out the apocalypse with my boyfriend.
But when the apocalypse came, no matter what I did, I couldn't open my space.
My boyfriend thought I'd deceived him and threw me out into the snow, where I froze to death.
As I lay dying, I saw my boyfriend cuddling with his pregnant mistress as she pulled out the supplies I'd worked so hard to prepare.
It turned out she'd awakened the ability to steal other people's spaces, and had been waiting for me to finish everything so she could take over.
When I opened my eyes again, I was back on the day I told my boyfriend I'd awakened an ability.
