How would you feel when a person you really love forgets you?

Minho and Sandara were dating happily for 2 months. They thought nothing could go wrong and nothing could come between them. But they were wrong. After a tragic incident, Sandara disappeared and couldnt be found. 

Many years later, Minho saw her again. She was there in front of him. But she looked at him like she hadn't seen her all her life.

Can this couple get together again?
