Seduce the Underworld King or Die

Princess Gloria is pulled into the Underworld at her 18th birthday banquet. Hades demands five deadly trials before anyone can return. Bound by the Underworld Heartbeat System, Gloria must seduce Hades or lose her soul. Through cruel trials, she survives by wit, while Hades grows ambiguous toward her. She learns she is a fragment of the goddess Grace, and the trials were Hades' plea to Zeus to bring Grace back. Yet Gloria rejects godhood and Hades' love, choosing the mortal world.
