ZBES-014 Despair Eros Little Devil Everyone calls me that Azuki

School girl Mariko falls in love at first sight with Ken, a bachelor who she happens to see on the train. She is selfish and self-satisfied, and she rushes to her house every day. At first, Ken, who didn't care about falling in love with a woman, was moved by a series of cute and pure charms, and she ended up living with Mariko. One day, Ken left Mariko's collar with a leash tied to a pillar and made her stay home alone, plotting to use two of his bad friends to tie her up.
