Dissociative amnesia is one of a group of conditions called dissociative disorders. Dissociative disorders are mental illnesses that involve disruptions or breakdowns of memory, consciousness, awareness, identity, and/or perception. When one or more of these functions is disrupted, symptoms can result. These symptoms can interfere with a person's general functioning, including social and work activities, and relationships.

Hyekyo lost her memory. She doesn't remember about how 'devastated' her family in the past, she also didn't even remember about her relationship with her man. It started when she saw her man cheated on her with another girl, with her own eyes. A 'one' feeling churned inside her heart. She thought about it. About her man who was cheating. With this incident (thing), she concluded that there will not be a successful relationship. She hates in a relationship with another person.

She was supposed to be learned from what has happened in her family. Her family was destroyed. Her family is intact, but that's painful. She shouldn't fall on the same mistakes, like what happened to her parents. Now, she's got to feel the pain that is her mother ever had. It's hurts.

“You’re awake!” Hyekyo turned to someone who is now sitting beside her bed. A someone who has a pretty yet handsome face. A someone who has a concerns in his eyes. Concerns? But, why should he? 

"I am sorry but, who are you?"

Now, he feels the world seemed to collapse on his head. Joongki lost his mind. He lost his words. He felt, as if he couldn't feel his heartbeat again. He looked right in her eyes. An eyes that used to smile for him. The eyes of her, that'll still be beautiful all the time. That eyes belong to Song Hye Kyo, his one and only love in his life.

"I am Song Joong Ki, yo-your boyfriend." His voice shakes as if he was going to cry. He tried to reach her right hand, but she pull it up faster.

Hyekyo looked at his eyes, "boyfriend?"

He bowed his head. A tears started running down his face. His voice shakes so hard, and Hyekyo can hear it clearly.

"I know this is all my mistake. But, but... please, don't do this to me, Hyekyo. Please,"

Hyekyo raised her brows, "I don't get what are you talking about, and I don't know who are youㅡ"

"So, please get out of my room. I can't talk to strangers. Go," she continued her words. The stranger-that Hyekyo called him- now facing her with teary eyes.

Strangers? He thought of it. Over. And over. He smiled at her, besides his tears still running. Now, he is a strangers. For her.

Before he left his seat, he kissed for her forehead with his tears falling to her nose tip.

"I really am sorry for this, Hyekyo."
