She was drugged by a female who was infatuated with the male lead for being her new step sister, (such a s*upid b!tch without her interferrence FL and ML would be just ordinary step siblings), after she was drugged and was helped by ML via bedding her (and not bringing her to a hospital ?), He actually has the gall to blame her for seducing him and he forces her to have a strictly s*xual relationship with him by blackmailing the FL by telling her that he will tell their newly wedded parents about her seducing him and her destroying her mother's new happiness which is the FL weakness so she aggreed reluctantly.

that she doesn't have the right to think about his lil' brother because he won't let things used by him to be recycled and given to his brother. What an assh#*le! I really want to punch him when he said that to her!

He is her childhood friend who I think was a doctor. He was really worried for the FL when he saw her with the ML in the streets and later found out about their relationship. He wants to help her but the FL is lying to him about not being forced so I am not sure what will happen because I stopped reading here.
