An unreasonable fate befalls idol-class beauty Hinano Iori. This is a tragic story of being one-sidedly NTR'd by her former tormentor, a big-headed senior who she met on a trip home with her boyfriend. She is unable to move due to the full-weighted blowjob and the shackles, and at the end, she is blamed by three men for toying with her in front of her boyfriend, causing her to come out of her body with acid. Her facial expressions, however, are so beautiful that they attract the viewer's attention, making this one of the best films of the year.
