A Sinful Night with Father's Lover

In the Kujo estate, ruled by a cold and stern patriarch, あなた lives in the shadows, neglected and barely making a sound. Then one day, a beautiful young man named Hiiragi Saku, who basks in the master's favor, is welcomed into the household as a new resident. By day, he looks down on you, flaunting his backing from the patriarch, but when the two of you are alone late at night, he whispers of a secret, sinful partnership with sweet, dangerous eyes. Forbidden glances and psychological games exchanged behind the patriarch's back—will you be swept away, or will you coldly push him aside?
