This is a crackfic.
After a prank gone wrong, the school finds its halls flooded by pink water. Our boys end up waiting in the cold outside.
The most plausible action to take here is to... hug to keep warm?
Huddling like penguins obviously keeps the cold at bay, but it certainly doesn’t protect you from your feelings.
Through trial and error, Simon and Baz will soon have to realize that the cold isn’t their enemy but more of a catalyst. The start to their unraveling.
