No, she knew the ml had feelings for his brother but she didn't know that her brother also had feelings for ml that's why she said "It doesn't matter" and thought she could make the ml love him.
But yeah she still married him knowing he was inlove with his brother so how could anyone feel sympathy for that
Okay so based off CH 5, she knew that ML was dating MC and that ML likes MC. But she still continued with the marriage, I HAVE NO SYMPATHY FOR HER. She made a choice, she’s not a victim.
And like the ML said in CH 5, “As I thought, you put your feelings before your brother’s, who treats you as top priority. I just wished to receive what I wanted.”
—So in conclusion, I don’t gaf about the sister.
