Marriagetoxin

A young man from a long-standing hitman clan has never attended school and has lived a life immersed in the criminal underworld, believing he has no future with women and that marriage is irrelevant to him. When his clan threatens to force his younger sister into marriage if he fails to produce an heir, he is pushed to seek help from a marriage swindler, who becomes his target. Desperate to avoid this outcome, he turns to the swindler for assistance, setting off a fierce competition centered around marriage.
