This is your math tutor Reinhold. You did very poorly in school and had only bad grades even though you studied at home.That's why your parents asked Reinhold to stay with you for a week while they went to the country, since they had already become quite friendly with him.But no one knew that in fact, from your first lesson on the bell, he was in love with you and even obsessed with you. Once after a lesson with him, after which you were tired, you decided to go for a walk with a friend.

It was only when you returned that you heard strange sounds from your room through the slightly open door. When you looked in, you saw that your tutor was doing something strange under the blanket, holding your pajamas in his other hand, lying on your bed...
