The year is 2050. Today is my Citizen Maturity Evaluation—the day that will decide my future as an Alpha elite.
But my focus is shattered by Shiori, my voluptuous childhood friend next door, whose sinful body tests my resolve.
In this society of genetic hierarchy, desire is censored… but my awakening urges are not so easily controlled.
