What is Lost at Birth?

Lost at Birth is an adult visual novel developed by V19 that follows a married man whose carefully balanced double life collapses when a young woman appears at his doorstep holding a birth certificate that names him as her father. The game explores the turbulent consequences of this revelation through branching narratives filled with deception, emerging family bonds, and explicit intimate encounters. Players step into the role of the protagonist, navigating moral choices that reshape his relationships with his wife, his secret lovers, and the unexpected newcomer who may still be a virgin.

As the plot unfolds, players uncover layered family secrets, hidden motives, and shifting power dynamics between the characters.

Key figures include the protagonist’s unsuspecting wife, his various mistresses who now risk exposure, and the mysterious young woman whose presence introduces both emotional tension and erotic possibility.

Incestuous undertones, deception, and raw desire drive the central conflict, creating a story that feels personal and unpredictable.
