"My boyfriend cheated on me with another woman, we had a fight and we needed money, so I thought I could pay for him... That's why I decided to appear in this film." "I want to devote myself to him... I love him because he always gives me challenges!" "I wonder what will happen if I show him the rope marks after filming is over?" A real SM documentary of the free-spirited masochistic actress, Mitake Yuuna!
