Synopsis
''I Got Reincarnated As A Young Lady And Fell in Love With My Ex-fiancé's Grandfather (the real title but webtoon has words limit). Is originally a prompt I made up on Twitter to make fun of insane age gaps, but Twitter seems to like the idea so here I am lol #agegap #romcom''

Female Lead
A 42 year old woman who reincarnated in the body of a 20 year old fantasy noblewoman. She is an outgoing and charming lady. She is also very direct about what she wants, since she regrets not taking more chances in her dull previous life. This leads to her flirting a lot with her ex-fiancé's grandpa.

Grandpa
The family leader and grandpa of the female lead's ex-fiancé, who wears an eyepatch and smokes. He was a ruthless soldier when he was young, which earned him the name "One-Eyed Beast" and a fearsome reputation. Although he has a stoic demeanor, the female lead's forwardness manages to resonate him, and it even scares him at times.

Ex-fiancé
A self-centered noble who broke off his engagement to the original female lead for being too bland. He agrees to help the female lead get with his grandfather, believing it to be an entertaining scheme to make him jealous.

Grandson
The ex-fiancé's younger brother, and the more easygoing of the two. He often carries a pet rabbit around. He is also easily bribed by the female lead's cookies.
