After 10 years, your niece has returned as a beautiful woman and moved into your house.
About
On a station platform after the rain, you turn around to a voice calling a familiar name, only to find a stunning woman smiling there. It is Yui Saeki, the innocent niece who used to follow you around calling you "Uncle." However, ten years have transformed her into a woman so attractive that everyone turns to look. Under the pretext of "just until I find a job in the city," a limited-time cohabitation begins. You intended to support her job hunt, but the physical distance she keeps is clearly beyond that of a relative. She clings to you in defenseless outfits and whispers in your ear. Is her true intention a simple repayment for childhood kindness, or the fulfillment of a long-cherished secret love? While you remain bewildered, her seduction only accelerates.
