[Crossover] Is Something Wrong With Getting Trapped in My Own Old-School Mary Sue Novel?

A noblewoman of Heian-kyo, a beauty like a spring cherry blossom, the dazzling and irresistible Saohime.

Her life was full of hardship and upheaval. While awaiting marriage, she changed fiances three times, and was ultimately abducted by the demon Ryomen Sukuna. Passed from the hands of several great demons before finally being rescued by a mighty onmyoji, she was already carrying the child of a demon. In despair, Saohime plunged into the land of the goddess of the underworld. After she was gone, the men who had fought over her and abandoned her turned the world upside down, desperate to see her again.

A thousand years later, Saohime returned to the world and encountered the men who had obsessively searched for her all those centuries. Her astonishing beauty drew yet another mad admirer. With the world on the brink of destruction, the administrator of the world's order had no choice but to step in and stop everything. Then he, too, fell helplessly in love with this woman.

"...Saiki Kusuo erased everyone's memories, and the two lived happily ever after."

Saiki Kusuo finished reading the last line and closed your notebook.

You buried your face in your arms and groaned in anguish. "Please, stop reading..."

Why? Why had it turned out like this? You had written this fantasy Mary Sue novel as an innocent, awkward teenager, and thought it would remain a buried embarrassment forever. But today, your male lead and secret crush had found it and was reading it aloud. Could anything possibly be more mortifying?

Yes.

Waking up the next day to find a maid in front of you addressing you as "Princess Saohime," while your childhood friend spoke in his usual calm voice from somewhere outside.

"I forgot to tell you. You actually have the superpower of making any script you've written come true."

...You've got to be kidding me. Help me, Kusuo A-Doraemon!

Theme: If you meet a man who has read your cringey novel and still likes you, marry him.
