The Doomed Mob Villainess Just Wants to Experience First Love

When I woke up, I had been reincarnated as a minor villainess in my favorite romance novel!? The character I reincarnated into, Leila, is a side character destined to be mean to the heroine, hated by her fiancé, and die in a carriage accident. Using the time I have to move freely, I try to resist and change the story, but I can't seem to change the plot. However, one day, I realize that I can change the parts that are unrelated to the story. For my own sake, and for Leila's, I, who couldn't have a happy romance in my previous life, decide to find her destined partner!!
