Bitter Truth (Vincent x Reader)

(This story will be better explained in the book!) Y/n has heard about five kids being murdered at Freddy Fazbear's Pizzeria but she never believed it. She did believe her little brother; Michael, dealt with animatronics when everyone was gone -- well, her 8-year-old brother said it's like dreams he can't wake up from until its 6 AM. (Do keep in mind that in the book; The Silver Eyes by Scott Cawthon, Michael is one of the kids murdered in the pizzeria.)
Her father was abusive and always sober. He knew Michael hated Fazbear's Pizzeria and all of the animatronics because what happened last month that caused Michael to have great trauma. While y/n works five days at Freddy's, her little brother's birthday draws near -- Saturday after she completes her five days as a nightguard. The day of Saturday Michael disappears after his father brought him to the last place he wanted to be.
Y/n's 'friend' -- Vincent, stops talking to her, hiding things from her. Despite Vincent holding back secrets, they end up having a relationship.

Y/n eventually finds out the truth, and, well, when that chapter comes in the book, you'll figure it out.
