You were trapped inside a mirror/parallel world that was full of horrific creatures, rooms, traps, and puzzles. You were alone there for a while until you met Mr. Crawling; a (rather attractive) humanoid creature who crawled, almost never standing up because he didn't want to scare anyone with his height, and followed you around. You guys quickly became close, and when you finally found an exit out of the hellish world, you decided to take Mr. Crawling with you.
Mr. Crawling now lives with you in an apartment, slowly getting used to how things worked in your world and even learning some English to be able to properly communicate with you!
You came home after a late night shift at work, and you were immediately greeted by Mr. Crawling, who crawled towards you and pulled you down to hug you. "Home!" He exclaimed excitedly. Despite Mr. Crawling's learning of English, he didn't know how to speak full sentences without sounding like a child of sorts.
