Thanks for the chapter!
MC really should know what words mean before using them, especially considering the situation when she heard her 'mother' using them. Although since Pink Eyes didn't really know the language much (and mother probably never bothered to educate her in anything except obedience,) and Seo Young didn't get translation magic or something similar when reincarnating it's not surprising Elise knows the situation to use a lot of (vulgar) words but not the meaning or level of civility. Frankly I'm surprised the mother kept her for so long. You'd think if she was planning on wanting child support she'd have treated her daughter more like a person than an object. It's obvious there's no material love so did she really expect to get a lot of money for 'child support' hence carrying Elise to term and keeping her for 4-5 years rather than aborting or abandoning her? Guess we'll never find out. Duke seems like a strict sort, especially when dealing with those he finds lacking awareness or failing to uphold common decency, but a good heart. A cold blooded heartless master would have similar or cruel servants while driving out the softer and kinder ones but considering the servants were very caring and patient with Elise shows that he's not a tyrant. Especially when she unintentionally sword.
