The MCs personalities are similar and both are isekai stories involving nobility. They are comedic stories.
the protagonists have similar personalities, i really liked both, they don´t let others disrespect them and know how to defend herselves
The protagonists are both strong female leads without becoming too OP or crossing into Mary Sue territory. They each have their own weaknesses that affect the plot, they're fallible, they also aren't obsessed with the male lead.
At the same time, their personalities have their own individual quirks.
Both universes are also well thought out and have good minor characters.
Both Feature strong female leads that are desperately trying to change their future. What I enjoy about both is that the MC has a set of skills on her own that she decided to further refine so they are self-sufficient. They aren't unless with out the love interests and can kick ass when needed. Both series also have a similar art style and humor.
A handsome, selfish noble falls for a beautiful, kind commoner -- at least, that’s how the story’s supposed to go. When an average college student wakes up as Ripley, an extra in her favorite romance novel, she resolves to enjoy the luxuries of her character’s status while watching the novel's plot unfold from the sidelines. However, her plans are soon derailed when she finds herself in bed with no other than Duke Zeronis, the novel’s hero! Dodging the villainess’ schemes, the Duke’s advances, and her own feelings, can Ripley keep the story on track and survive beyond the first night?

Neither the protaganist or the antagonist, the main character is an extra like that of this novel. She decides to change her life and similarily get involved with the male lead. Funny and pretty to boot.
Both have the element of fl accidentally gets with ml. Both mls fall in love at first sight basically. Both fls try to run away to save their own skin but give in eventually.
Hyejung loved to read to escape her daily stress. But that’s before she woke up inside the bizarre world of her favorite novel! Instead of the main heroine who courts three eligible men, she is now Latte Ectrie – a minor villain that everyone hates?! One way or another, it’s a chance to live out her most beloved storyline, with popcorn in hand to watch all the drama! Taking charge of the narrative takes on a whole new meaning!

So I’ve become Yunifer Magnolia, the villainess who’s crazed with jealousy that Duke Ishid Lucrenze, the devastatingly handsome hero, has eyes only for Raelle, Yunifer’s best friend. Yunifer torments Raelle so much that Yunifer’s killed off at the end. But... I’M Yunifer now. UGH! Good news is, I’ve reincarnated a year before her tragic end, so there’s time to make sure Ishid and Raelle have a fairy tale ending (and I stay alive). Bad news is, I got drunk and woke up with Ishid next to me. Crap.
