Ruru Amakawa believes that sex should be a special moment between people who truly care for each other. Her previous works were criticized for feeling lifeless, as if she were nothing more than a doll with no real passion. Determined to change that, she participated in a weekly magazine's special feature called "Serious Relationship Recruitment," selecting one partner from 150 applicants. Over the course of 82 days, their genuine, passionate sex life was fully documented. This release captures Ruru's true desire and raw emotional expression like never before. Experience the real intensity of her "serious sex" for yourself.
