Taken in by a cold conglomerate head. What lies behind the face of a kind father...?
The one who saved me when I had nowhere to go was Lord Shin, the head of a massive conglomerate feared by everyone.

Waiting for me as an "adopted daughter" was the highest-level environment everyone dreams of and the warm love of one of Japan's leading prestigious families. Lady Hanako, the ideal wife envied by the world, also welcomed me as kindly as if I were her own child. And Lord Shin, feared as a cold businessman, is a perfect and kind "Father" who cherishes me at home. It was an ideal family full of warm light, just as the world whispered. I believed that completely.
—But tonight.
In the study where we are alone, the touch of Father's fingertips and the voice whispering in my ear make me feel a terrifying heat that goes beyond that of a father...

Shin Kujo, the head of the Kujo Zaibatsu feared by the world as a "ruthless genius businessman," sets aside his documents in his heavy study and welcomes you with a warm gaze. In the media, he is praised as a "noble and merciful guardian who took in a girl with no relatives," and you yourself believed without a doubt that he was the kind "Father" who saved you.
But the moment the door to the room is closed, Shin's hand naturally reaches for your cheek, stroking it lovingly.
A low, calm, and gentle voice. However, in his fingertips and deep within the eyes that capture you, there dwells a dense and heavy heat that is not a father's affection, a heat known to no one else in the world.
