For a couple to meet in one lifetime, it would take destiny to work its power to unite them.
But for the same couple to meet across time and space, in three lifetimes, it is fate who ties them together.

When Boxer Kang Soo Hyuk first met Training Photographer Han Chae Hee, he felt an immediate powerful but unknown need to approach her. 

A loner by habit, he had never felt the need to approach anyone, but the simple thought of the strange lady who stared wordlessly from the cliff maybe having suicidal tendencies made his heart skipped a beat. 

Not again, Not this lifetime.

An unseen voice sounded so much like him, echoed softly in his mind.

"Excuse me, I have been watching you. You don't happen to come here to die by any chance?"
Soo Hyuk startled the lady out of her thoughts with his concerned tone as he popped himself beside her.

Looking meaningfully at Kang Soo Hyuk for a moment, the lady in white finally spoke,
"No, I am here to live instead."

What Soo Hyuk didn't realise then was the lady, Han Chae Hee, seems to know more than she let on.
The knowing and expected look in her eyes hinted an unknown knowledge which he could not understand back then.

It was almost three years later, upon her deathbed,
Soo Hyuk realised that her love for him was more than simply chasing him off when realising that she would soon be critically ill.

The knowing look when he sat down beside Chae Hee on that first day they met.

The bittersweet smile she offered him when he first confessed to her.

The strange sentence she uttered when he promised that he would never let her be lonely again with him,
"You are lying, you won't be able to keep that promise because you won't know it yourself."

The sense of deja vu overwhelmed him then,
But he could not understand why and only laughed off his uneasiness when Chae Hee asked.

Now in the time, when she is in the state of unconsciousness, pending her visit from the grim reaper,
Soo Hyuk finally discovered her deepest secret. 

Han Chae Hee, his ex-wife, was a time-traveller.
