I'm all confused right now. It might be alright for Eun Gi to not remember the face of who saved her in the plane because she was barely conscious when she fell on the plane floor, but she did learn the identity of her savior after (I remember her saying to Jae Hee "he wasn't even a doctor, did you try to kill me?"). She should have known the name "Kang Ma Ru" by then, especially since she sued him in the name of Jae Hee to get at her because she believed they were in this act together to "kill her" or something like that. However, judging by the end of episode 6, Eun Gi was completely clueless they were into that kind of relationship before. I still don't get that after she met Ma Ru in the bike accident, she didn't realize he was the guy that saved her/that she sued. Everyone talks about the amnesia thing they announced in the synopsis, but didn't it actually already happen?
