Blind Yandere X Reader - changing the gender preference of the reader will not impact the story - changing the gender preference of the yandere will not impact the story - cover made by me, see links to images used at the bottom of the description - this is purely a work of fiction, anything relating to anyone is just coincidence - this work is NOT written as a romance and should not be treated as such - all characters are owned by me unless otherwise stated - you own yourself ^ - Moment /ˈməʊm(ə)nt/ a very brief period of time Everything only takes a moment to change completely, a bad decision, a discovery, an accident. He's a nice guy, but then again, don't judge a book by its cover, just like you won't know how sour a strawberry is until you bite into it.
