Summary
Kuzuryuu usually turns to alcohol as an escape, as a way of fuelling his Despair. He delves into the hazy sensations and lounges around, pushing his duties onto everyone else. But this time, instead of being zoned out of his mind, he finds clarity.
He seeks Peko to try and break him out of it, only to find her going through it as well.

Summary
from 2024 onwards (i.e. the vast majority of my fic catalogue), i usually have to be very happy with a work to publish it. or at the very least i think there's at least 1 good concept in it
but i am also aware that i can write fast, and upload a lot. so, 'tis an attempt to cut them down to the ones i like the absolutely most to try make my fic catalogue a bit more approachable
(biased towards The Hundred Line -Last Defense Academy- because that's my hyperfixation rn)

Bookmarker's Notes
ahhh taps into one of the things i think is easiest to miss about peko's character; she will prioritise keeping fuyuhiko safe in a dire situation over actually obeying his orders. so yeah, real nice
