Do Sejin doesn't understand. Why is his sister dead? Who would do this to her? To kill her this way... He can't imagine the pain his little sister experienced.

He sees Ahn Hana staring at her fingers. Crack. Crack Crack. She moves each finger up and down repetitively. She touches her belly and her heart, trying to imagine it. He grasps her wrist and drags her away from the corridor.

Finding an isolated corner, he pushes her against the wall and glares into her hollow eyes. He curls his fingers on her throat. If she dares to hide anything this time, he will stop caring about anything. He just knows it. She is connected to his sister's death.

He asks in a frighteningly low voice. "Ahn Hana, who did this to my sister?"

Eerily calm. She looks at the boy.

Do Sejin. 21. A final year law student. Top in his class. 6 feet tall. Clear skin. intense and deep eyes. Lean. Slender. Long legs. Easily attracts girls with his heart throbbing smile. A notorious playboy.

"He was angry this time." She answers his question. Her voice is dark. As dark as the voice of the man who is trying to possess her. "He gave her pain because of the pain that you gave me."

He falls on his knees. His sister died because of him? Silent tears fall on the floor. "He should have killed me if he was angry. Why my sister?"

"Because." She bends down on her knees and hugs him. "The pain that you feel now is more painful than any other pain."

[Only pain can remove the pain. Remember that, My dear Hana.]

People run to the spot when they hear raging howls. They see Ahn Hana and Do Sejin, hugging each other. He clutches on her clothes and cries like a little boy. This pain is tearing him apart. No amount of regrets and tears can bring his sister back.

"How many times have you met the killer?" The detective asks the woman. She is still looking down at her pale hands. Jung Kwang-soo places his hands on her shoulders and gives her a nudge. She is broken out of her thoughts.

"First time. 10 years ago." She fists her hands when she remembers that night. "Second time. Around 6 weeks ago."

"Are you sure that you didn't meet him other time?" The detective has heard all the details from Jung Kwang-soo. The 100th-day murder. This Woman. The love letters. The obsessive serial killer.

He hasn't made any judgment yet. "Think hard."

Ahn Hana remembers the coat. He has visited her at her home. She doesn't know when.

"He might have come to my apartment. I don't know how many times and when."

"I see." He scribbles down something in his notebook. "Do you suspect anyone? A close friend?"

He glances Jung Kwang-soo. Jung Kwang-soo shakes his shoulders as casually as he could.

"None I can think of." Nobody comes to her mind. Magnolia flower. That figure. Voice. Chuckle. His touch. She is disgusted beyond words.

"Okay. Are you comfortable talking about the times when you met the killer?" Detective asks her carefully. "His exact words? Everything that you remember?"

Everything that she remembers... She trembles when a disturbing thought comes in her mind. What about the times that she doesn't remember? How many times has she met him?

"Miss Ahn, you are also a victim." The detective decides to give her a push. "You need to speak to get justice."

Victim. Justice. Funny words. She smiles darkly at the detective. She will say it. Everything. Her parents' death. The 100th-day murder. Her accident. The time when she was in a coma. Her wedding day. The love letters. Noe Kyung-Hee's story. His Revenge. His promises. She will reveal it all to the world. Like he wants her to.

Standing at the back, Do Sejin hears it all. She doesn't hold back. Instead of humiliation or pain, he only sees the madness in her eyes. Trace of sanity comes and go. The killer has done something irreversible to her. Though she hasn't completely fallen yet, she is temped in each second of her life. Something is holding her back.

His sister is gone. He couldn't protect her. He won't let Ahn Hana disappear from this world either. He swears that he will catch that killer and make him pay for hurting the two most important persons of his life.

The tip of the knife touches her belly. Thump. Thump. Thump. Her heart is going crazy. She can't press it.

"Ahn Hana!" Jung Kwang-soo grabs the knife and throws it away. "Are you crazy?"

"I think that I am going crazy." She leans on his ċhėst weakly. "He will come for me."

"I am here." Jung Kwang-soo hugs her tightly. "Don't be afraid. They will find the killer soon. I will go to the hearing. You are safe. There are guards at the door. Tomorrow, we will take you to a safe place."

Is she? She doesn't trust him.

"Tomorrow, let's get you to the hospital. Your treatment is also necessary." He carries her to the bed and tucks her under the blanket. "Sleep tight. I am guarding you. I would die protecting you. I promise."

She curls her toes inward. It's hard to believe in his abilities. "Jung Kwang-soo, I would prefer if you care about your life more than mine. If he comes, run for your life."

"No." He inhales sharply. "It's my fault. I should not have left you alone at that hotel. I should have tried to break the door if you didn't open it. Because of me, he... "

He closes his eyes in frustration. He should have never left her alone. He should not have taken her to the hotel in the first place. He should have dropped her at the dormitory.

"He would have found another way." She turns to her right, showing her back to me. "Don't think of what-ifs. There is no end to it. Let's just sleep for tonight."

Jung Kwang-soo sighs loudly. He turns off the light and goes back to the living room. He decides to stay awake for the whole night. After everything that happened today, he can't sleep anyway.
