When Is A Monster Not A Monster, When You Used To Sing It To Sleep

Since the dawn of time, monsters have been assigned to humans. We live in any space we can, under the bed, in the closet and I've even spoken to some who have lived under a fridge.
We tend to stay with our assigned humans from the beginning of their life until the end of it, and sometimes, especially those who become 'too attached' it spells the end of us too.
This is my first and, unfortunately, last assignment. My human is Zhong Chenle.

-Can be read as a stand alone or sequel to When Is A Monster Not A Monster, When You Love It-
