The protagonist (and anti-hero) of the game. She attends the wedding of her old university friend, but things quickly take a sinister turn. She is calculated, highly intelligent, and deeply vengeful. She has shoulder-length black hair tied into a messy ponytail. Her striking outfit consists of a black vinyl trench coat over a short-sleeved white turtleneck, paired with black trousers, red gloves, and a red belt tied around her waist.

Da-jeong is a doctor who cares deeply for her partner, but she finds herself trapped in a terrifying situation. She is the bride with pale skin, dark brown eyes, and long black hair usually worn down or in a messy bun with escaping strands. She wears a layered white ballgown with puff sleeves, fingerless gloves, and a tulle birdcage veil. A complex and contradictory character who can come off as snobby, sarcastic, and clumsy, yet is perceived by others as optimistic, friendly, and a hopeless romantic.

Da-jeong’s soon-to-be husband (and later husband-to-be). He becomes the tragic central figure of the game's unfolding horrors. He is a generous, and overly trusting man. He is tall, light-skinned man with short black hair and black eyes. He wears black rectangular glasses.
