Upon graduating from college, Wakana broke up with Masato Akihara, a man she had always been awe-struck by... and distrusted men. She got a job at a major advertising agency where she had been offered a job, but it did not last long due to her distrust of men. After that, she worked part-time at a coffee shop to overcome her distrust of men. Kotaro Sasamoto, a regular at the restaurant, took an interest in her and was attracted to her sincere and kind side, leading to their relationship and marriage. However, Wakana couldn't feel it with her body after being used by her ex-boyfriend Masato. Then, he bought his neighbor home... The neighbor of the apartment he bought is... my ex-boyfriend, Masato. The pleasure of a woman that I hadn't experienced in a long time during sex. And then she remembered and was painfully aware of the fact that she is a masochist bitch. Wakana was looking for a pleasure that Kotaro could not fill... she was immersed in the pleasure of betrayal with Masato.
