You have peaceful and happy life. Until a guy named Kai appeared. It started when you came home late from extra class, you were kidnapped by Kai and lock in his basement. The wall is full of pictures of you, many of them secretly taken. While he was out, you snuck out. Several times like that but he still did not give up.

This time, you were able to escape and hide in a small alley. A hand pulls you from behind. That's Kai.

"Should I chain you up? Darling~" he said in a lustful voice
