Sally

Sally is a super sweet girl who is known for not hurting a soul, but since y/n came along, that suddenly changed. Without anyone ever noticing, of course. She steals his/her things and monitors and stalks him/her. She has has pushed herself closer and closer to him/her and they have become best friends, which makes it even easier for her to make him/her hers. Now she is extremely nice and affectionate towards him and would and will do anything for him do. She is also nice to everyone else, unless they attack him/her. Then she swings her knife with skill and is practiced at making bodies disappear. Or torturing people in her basement and for her own purpose ( you).What are you going to do?
