Sucking up to the Villain to Live a Comfortable Life (SVLCL)

Is a story about a 27 year old woman who died during a plane accident in midair. Instead of rotting in hell, Rai was reincarnated to another world in a body of a three year old little girl. She soon realized that the world she's in is actually a very low-key but good novel she stumbled upon in the internet.

Knowing the contents and events of the novel, Rai decided to stick with the infamous villain, Prince Ellios, to change his doomed ending and help him become a better person than he originally was in the novel.

While in the process of doing so, Rai inevitably meets the Prince's big sister, Princess Eclaire, who is the female lead of the story.

Rai may have also fallen in love with the Female Lead at first sight...
