That's why I like her😆
I mean I know she is bad. But she never irritates me like Kareena. She is interesting and entertaining as a character
She knows people very well.
That's so true. In fact I'm damn sure every kundali bhagya viewer hates kareena more than sherlyn because sherlyn is just your typical evil vamp with selfish intentions and is two-faced, but kareena is actually outright cold and heartless towards preeta and so malicious in her words that you feel more disgust seeing kareena's senseless venom-spewing against preeta, rather than sherlyn's character assassination plotting against preeta.
So for that reason sherlyn is more bearable, especially given that preeta is an obstacle in her goals so that's why she hates preeta and does evil things against her, but on the other hand kareena outright humiliates and belittles preeta for no reason other than for something as petty as socio-economic status. It's the justifications and appproaches of the two characters that makes one more likeable/ bearable than the other.
