After the Ninety-Ninth Loop, I Went Crazy on the Spot!

Nian Suisui is a novelist whose books keep flopping. She's passionate about writing, but every book is a failure. She's lost count of how many novels she's started, and some of them were even abandoned before the ending. One day, after yet another novel flopped, Nian Suisui finally snapped. She grabbed her keyboard and hurled it, and wouldn't you know it, thunder cracked outside the window. With a bang, Nian Suisui fell over, leaving only a corpse on the floor. Si Jinyu was originally a fictional character, but one day she suddenly came to life, all because that author who'd left her story unfinished had entered the plot herself. P.S. I'm going to write about two female leads no matter what. Even if nobody reads it, I'll keep writing. Hmph! [Transmigrate into a book + somewhat mentally unstable + devoted to each other]
