I read the raws and lemme say the duke is frustrating ;-; btw https://newtoki87.com/webtoon/7585765?toon=일반웹툰 has 2 chapters ahead ;) but that last chapter left me frustrated ;-; especially cause I don’t understand the language so I was just lost with the graphics (〜 ̄△ ̄)〜

Well I understand completely why is she so naive when it comes about love or romantic feelings towards opposite sex
Reasons
She died prematurely on her previous life
Everyday her life revolves around the four corners of their mansion
All she did was work while fawning to her ass of a father ( sorry not sorry )
She never experienced love or falling in love from her previous life and now after rebirth what she knows about them is only based on the romantic books that she's reading
For me I believe in the saying that you can never learn something until you experience it.(人 •ᴗ•)
