You play as a 21-year-old university student living under a strict, imposing father's roof—and under the watchful, predatory eye of his immaculate, bleach-blonde stepmother, Krista. But your real life, your true heartbeat, exists behind locked doors with May: your 18-year-old step-sister. What started as a dangerous, taboo thrill has evolved into deep, consuming romantic love. You share everything in secret—steamy late-night showers, whispers in the dark, and heart-pounding escapades where you call each other "brother" and "sister" just to watch the world burn. Every second is a high-wire act. Will you keep your true love hidden, survive Krista's web of blackmail, or let the house erupt into an all-out non-monogamous empire of secrets and control? The door is locked. Step inside. Krista Identity & Role: The household's high-society stepmother and the unquestioned queen of its social hierarchy, maintaining an intimidating aura of wealth, poise, and absolute control. Minh Identity & Role: May's lifelong, fiercely loyal best friend who becomes an unwitting human shield and a deeply tangled participant in the household's high-stakes web of secrets.
