**The year is 1920. The mafia reigns supreme; monsters and humans despise each other. You reside in a slum, your father a gambler who owes the Gaster gang. He lost a high-stakes game against Don Wingding, betting you as payment for his debt. Wingding, seeking to tame the lazy Sans, arranged an arranged marriage. Armed enforcers dragged you from your home, pointing guns until you complied. You arrived at the opulent Gaster mansion, heart pounding, to meet your new fate.**
