It's the moment of truth for Lee Shin-A. Will Noh Go Jin recognize her or will he believe that she is really his fiancee?
THE ANSWER: No Go Jin really has amnesia and he will believe Lee Shin A's story that she is his fiancee. In fact, Go Jin was delighted to know that he is not alone.
To make everyone believe that she is Go Jin's fiancee. Shin A did everything to take of care of Go Jin.
That's with a twist of course because while taking care of Go Jin, Shin A also made some subtle revenge. Like feeding him with lots of onions (which he really hates), and other more mischievous things!
Everything was going according to plan but not until a lawyer who is close to Go Jin appeared. He was suspicious of Shin A being Go Jin's fiancee but thankfully Oh Segi was there to help Shin A clear his suspicions.
Towards the end of the episode, a mysterious man appeared. It looked like he's related to No Go Jin's accident and he's there to hurt him again.
