“To be my wife, you have to keep the three things I said earlier. Can you do it? If you don’t want to, go back now.”
What Sang-yeon wanted from Minju was a wife and a ghost bride. A being that exists, but does not exist.
“No, this is my home now. I’m not going back.”
Minju and Sang-yeon agreed to a secret marriage between the two unbeknownst to the rest of the world.

She should have been suspicious of Park Sang-yeon, a world-renowned conductor representing Korea, when he said he loved her.
