I seriously can't understand how the adopted sister and her boyfriend be so selfish and egocentric to actually think that she would forgive them. She set her up to get raped and she got pregnant afterwards, causing her to be hated by her parents. Then she tried to ruin her career. Not mention that mc's ex boyfriend cheated on her with her sister and knows she got the MC raped. Even refuses to testify.
They even have the nerve to think there the victim. Do they have a moral compass at all?
They may have surpassed Griffith and Johan as most evil characters in fiction. At least you understand why Griffith and Johan became that evil.
