The slender creature and the Mute

"Mino the Mute" they called her at school.
"Mino the killer" they called her in town
"Mino my princess" he and only he called her.
When Mino was accused of killing her parents and siblings she ran off giving the police even more reason I believe it was her.
"sure the knife was in my hand and sure I was covered in blood, but would I dare hurt the people I love."
Mino then finds herself been captured by a Slender creature and living in the basement of his beautiful mansion. Along the way she finds that she now cares for her kidnapper and the other people that live in the house.
