Who is the male lead? I hope it's not he prince. He is a hypocrite. He disliked the MC because she pursued him even when he made it clear that he wasn't interested. Now he's doing the same thing to her. He wants her now that she said she's not interested in him and keeps pursuing her even after it became clear she's not interested. He's also too quick to judge people without even understanding what's going on in the situation. He blamed the MC for her sister's ruined dress without even asking what happened.
I feel so bad for the MC. She just wanted to be loved. Even though her father had such a terrible relationship with her mother, that's no excuse to treat the MC this way. Her sister also makes things worse for her. The sister is such an airhead. The only people who supported her were her maid and childhood friend. I hope her childhood friend is he male lead.
