Although I Am a Mob Character, I'm Being Doted on by an Overprotective Duke summary:
I was reincarnated as a mob character from an otome game, and my fiancé is a handsome duke.
I've been transmigrated as "Leticia," a mob character from an otome game. I was forced to take Lionel as my fiancé by my twin sister (who, by the way, has the worst personality). The first time I met Lionel, he was nothing but chubby and fat, just as the rumours said he'd be… However, me being me, I realised that Lionel is an unpolished gem with potential to shine, so I decided to re-invent him. Even if I'm a mob character, my days of doting on my fiancé began when my fiancé transformed both inside and out.
