As I read through the summary, I figured that he raped her when she was unconscious and I was right! But am I the only one who thinks that he raped her once and she suddenly woke up the next day? Or I lacked the reading comprehension? Anyways, I have mixed feelings with this. The ML surely is one possessive and jealous dude and FL just goes along with everything everyone says.
