i think its Ossey right? He's two faced hsabsjhs and it's so obvious that he's using the MC's sister to interact or approach the MC

Isley is pretty naughty, he kind of jerk and like to make jokes, he's funny tho and easygoing BUT he's a madman lmao once he got jealous or anything related to MC, he really love to tease the MC, I kinda ship him with the MC tho cus their interaction is so funny and cute especially for the MC reaction when she got teased by Isley😭💗

Arthur is so pretty like an angel compared to his brother (Ossey looks like a gentle, kind and handsome and Isley looks like a cunning but seductive devil), he always feel lonely that I want to pat him, poor bby 😭 although his mouth is harsh, he's kind inside and tsundere lmao, he likes cat too, he always do kind things secretly for example like covered the MC fault by taking the blame although before that he's scolding the MC hahah and helping the MC sister too

• The "pointless reincarnation" is literally the entire point of why MC is feeling so guilty of their tragedy. She know the future at the Ducal mansion, so she avoid them, leading to them both to the worse future of getting locked up by the Count. If she doesn't have knowledge of the future, she would not have feel so guilty.
• Of course MC treat the book like reality. It is her reality. She only lost her memory of her previous live and the short time after they escape. The entire memory of r*pe and torture is still there. If she see a future where they continue to get locked up, r*ped and tortured again why wouldn't she be scared of it.
• The sisters escape the Dukedom is the most realistic part of the aftermath. Why would they even stay there? We know that the 2 brother stopped obsessing over MC almost immediately after the sisters left, but the sisters themself don't know that. Infact they was so shock and scare when Isley appear at their shop. Why would they, especially MC stay there?
• The MC personality change because she got back her memory bit by bit. Even other character in the story notice this. And it happen later on with a trigger (the connection to the Count reach the Dukedom), so it is not arrupt at all.
• Isley isn't really that sweet. He is just the one MC getting along with the best before her memory comeback. He is the best among the three, but to MC he is simply one of her future's nightmare. But he already get the best treatment among the three as well. MC did said that she know he really love her. But also she can't answer him because she scare of everything about him. That is her trauma, and she convey it to him clearly so she isn't stringing him along.
• And the side story is almost exclusively about Isley.
• Lastly, both sisters have deep trauma about noble. Just because he give up his noblility mean nothing when he could just take it all back if he decided to come home. The only reason the sister accept him is because MC accept him first.

Isley being a commoner for his love was a unique move for these kinds of books. I wish the writing didn't anger me this much that I could enjoy it.

-It really doesn’t make sense at the end when the sisters leave the country while they can live safely with Duke's support, not necessarily to stay in the castle but near it so they can cut ties with the brothers. I thought it was a dangerous move, since they are powerless little girls in that environment... Well, they did encounter danger after a while... So s*upid.

In the first part of the story, it likes other story that you can guess what will going on. The typical story of obsessive ML come to like our MC in the end. I also feel frustrated of MC in the middle part of the story. However, the ending is so good. The MC and her sister finally find their own happiness without depending on the man. Of course, this story has ml. You will know it in the side story.

I LOVE that the "ML" (though they don't officially get together on screen) ended up being the the 'rowdy fun middle kid' ish type of guy, I feel like it's rare these days as you usually default with the stoic eldest as the endgame.
