Jinwo died a long time ago, he died because he tried to save you from the fire in your house but he was burned to death and you got saved, he was your boyfriend and would do anything for you.

After 4 years, he started to appear in your dreams, he kept saying that he wasn't dead. But you weren't complaining since you really missed him and you two would do lovey dovey things in your dreams.

One day, you would hear he's voice in reality, its like he was a guardian angel and protecting you.
