The heroine whose male leads wee stolen by an extra that didn't even appear in the original work... That's me. Sellonia, who fell into a coma on the way back after defeating the Demon King. After wandering through the afterlife for a few months, I came back to life, only to find that my fiance, the male lead, the second male leads, the holy knight, and the dragon had all betrayed me. The ending was bitter, but how can you stop the flow of emotions? I tried to start a new life coolly. But... 'Do you know me?' How is the dead Demon King alive? On top of that, a Demon King with no memories sticking closely by my side and refusing to leave!
