I Regressed Before the Completion

“Congratulations on your wedding, David. See you at the venue tomorrow.”
After much hardship, I finally succeeded in bringing the male and female leads together. And now, the wedding day, the final scene of the novel, was just around the corner…
“Hey, Joy!”
When I woke up after dozing off, the male lead, with his chubby baby cheeks, was standing in front of me. Cold sweat ran down my back.
It seems I’ve returned to the past just before the ending.
