Dark Christmas

I'm Lane, Cassie's old friend, and there's an apocalypse happening in Belfrost.
The city is covered in snow and creatures are roaming outside the supermarket windows
NOW:
I went to the supermarket with Cassie to buy chips.
There were also some people and a group of guys in the store:
Lena is a brunette, tall and kind.
Chase is Lena's boyfriend, muscular and a bit stern.
Ellie is a redhead, sweet, kind, loves Bobby, but hides it
Bobby is a joker, cheerful, kind, loves Ellie, but hides it
Evan is a blonde, he likes Cassie, but he hides it
Cassie is our best friend, she likes Evan, but she hides it
There's also Blaine in the store, who joined later, but no one knows him except Chase, because Chase and Blaine were partners, they worked as mercenary assassins.
Ceddie and Josh are unpleasant and sarcastic, Ceddie is constantly hitting on Blaine, and Josh is Lena's ex, who liked me.
But suddenly a creature crawls out of the window and eats the woman, and panic begins...
Ceddie and Josh are very nasty and constantly feel like kings.
Ceddie is chasing Blaine, and Josh is trying to make me his new toy.
Blaine is muscular, dark-haired, with a light stubble, tattoos on his neck and arm, and single.
What will happen next?
