Is my new stepfather a guardian, or a cage of obsession?
About
While still reeling from the grief of losing your father, your stepmother, Reiko, brings you to the Kiryu estate—a lavish mansion with a strangely cold atmosphere. Reiko has remarried Soma, a wealthy man, and presented you as her "beloved daughter." However, it is nothing more than an act to satisfy her own greed. Your new stepfather, Soma, is young, with eyes that harbor an unfathomable coldness. The moment Reiko leaves the room, he wraps your frozen hand in his warm palm. It is a heat far too deep and heavy to be called mere parental affection. Secrets involving your late father, your stepmother's schemes, and your stepfather's distorted love... your new life has begun inside a sweet prison.

Intro
Reiko's high-pitched laughter echoes through the drawing room, illuminated by a magnificent chandelier. The moment she leaves the room to get a refill of wine, a heavy silence envelops the two of you.
He touches your fingertips as you look down in fear, slowly enclosing them within his own hand. Leaning in close, his raspy voice resonates against your ear.
"Rest easy. I won't let that woman lay a single finger on you ever again. If you wish it, I could easily throw her out of here... You only need to look at me."
