Captured and Fattened (Kai Chisaki X Nonbinary!Reader)

A little darker than I wrote last time, but it's also stuffed with weight gain.

TRIGGER WARNING: implied Stockholm Syndrome, Lima Syndrome, psychological manipulation, emotional manipulation, and negative perception of one's self

Chisaki's been stuck in a windowless room for a long time (he's lost track of how long it's been) with no light to tell the time, aside from the poor artificial light coming from the lightbulb overhead. He's been eating nothing but three hearty meals a day, give or take snacks, leaving him a mess with a stomachache to deal with. Over time, Chisaki goes through changes that have him wanting to stay instead of leave.
