The strongest adventurer duo, Anna and Relatone, take on a request from a corrupt noble — only to fall into a trap and be saddled with a massive debt. To free the captured Relatone, Anna desperately searches for a way to make money. But a busty, beautiful girl in financial trouble is the perfect prey — and there’s no way the lustful men around would let such an opportunity slip. Anna, sweet-talked and manipulated, ends up giving her body to a worthless man. Thus, the strongest busty beauty strays from the path… and falls into the hands of a useless man.
