The usual Studio Pork product, the male protagonist is Sunao Saiki, a young man who has just experienced the sad aftertaste of failing his college entrance exams, with nothing productive going on at his life right now Sunao decides to take a part time job in convenience store, there he meets the heroine of this Eroge: Ayano Shinonome, a gorgeous older married woman who will one of his work colleagues in the foreseeable future.
Sunao immediately falls in love with Ayano, and the two start to get closer; Ayano for one is living a marriage which has lost much of its flame, her husband isn’t as caring and supportive as he used to, now he is quite a slob. After a while it is revealed that Ayano, despite some resistance, also immediately took notice of Sunao, he is younger than her, but Sunao woke a distant memory of Ayano’s teenager years, he looks exactly like her first crush, a man much older than she was at the time, memories of a crush that never came to grow into anything more than that. That way the stage is set, Sunao and Ayano soon begin their secret affair, which despite it is amorality it is sort of framed as Ayano finding her true love, as the Eroge itself has many scenes from her point of view, rationalizing her affair with the ongoing disappointment over current weakening marriage.
One of the rare examples, where NTR is understandable and almost no stupid moments and genre's cliches. Protagonist is not some sex-god or asshole, nope, he is pretty decent guy with some problems, but still allright. The point of women also shown. Her husbant is... really almost forgot about her. So yes, good thing.
