Chapter 1

SEVERUS POV

After a few weeks of vacation, I was now back at my usual dungeon. Which means, only a few days from now, the dunderheads will all be back and my blissful moment alone will be gone again. As I entered my room, I felt something different. I know the dungeon was cold but it felt more colder now. Being a death eater and a spy, I felt being watched. Even if I was now in my room alone, I still felt someone was watching me. I pulled my wand from my pocket and started to unshrink my things with the wave of my wand. After I finished unpacking my things, I felt the hair at the back of my neck started to rose. Suddenly, something caught my eye. There in front of me was a transparent figure of a woman. She seemed familiar to me but I can't remember where I saw her. She was wearing a white gown reaching to his toes , she has a long brown straight hair and a gray eyes.

"Who are you?" I hissed at her because I haven't seen her lingering here in the castle.

"Sorry for coming here unwelcomed. You really don't remember me?" She asked calmly.

"Will I ask you who you are, if I can remember you?" I raised my eye brow and she chuckled slightly.

"Sorry. I'm Mary... Now, do you remember me?" Silence. I closed my eyes to think. A young child appeared in my mind.

"Impossible!" That's the only word I can say.

"No, Sev. Everything is possible." I stared at her, still not believing what my eyes saw. I startled a bit because of her calling me that name again.

"B-but...H-how?" She looked away and ansFwered.

"I-I don't know Sev. All I can remember is a light, blackness and then, I don't know what happen." She covered her face with her hands, silent sob escaping her. I want to comfort her but I don't know how to comfort a ghost. I can't touch her and I can't find a right word to say.

"Everything will be fine." She looked at me and shook her head. After a minute of crying, she stopped and looked at me again.

"So, you really remember me?" 'Is she crazy? How can I forgot her?' I thought.

"Of course! How can I forget someone like you?" She smiled again and I saw something in her eyes.

"Thank you Sev! It really means a lot to me! I really don't know why I'm here but I'm happy to see you again after so many years." She smiled weakly at me and I tried to smile back at her. I don't remember the last time I smiled.

We were friends long time ago. We were 7yrs. old when we first met each other. She was my first friend and she was like a sister to me. When we we're 9yrs. old, they moved to another place and that was the last time I saw her. Even if we were friends for only 2 years, she became close to me and we enjoyed being together.

"I'm glad you want to see me. Of all the people. I'm amused you still remember me. I thought I will never see you again."

"Of course I like to see you again. Even if many years have pass, I still can't forget someone like you. You were my first friend and my one and only bestfriend. Can we still be friends inspite of my appreance?" I felt hurt inside my heart by the mention of bestfriend. 'Lily' I thought. There were hundrends of question playing in my mind. I want to ask her but I think she also don't know the answer so I just simply answer her.

"Bestfriends forever right?" 'I Severus Snape have a ghost best friend. I my self really don't know why I said that. Surely were bestfriend but she's a ghost now, right?' I thought.

"Yeah!" She said happily. And I rolled my eyes. Suddenly, I remembered we were at Hogwarts and all the staff were required to be at the great hall by now. Every staffs were requested to be here at Hogwarts a few days before the students to come.

"I need to go to the great hall by now." I wondered if she will stay or leave. Inside my heart, I know I also missed her and I want to be with her a bit longer. I really enjoyed her company when we were young.

"I don't know when will I'm going to disappear but for now, can I stay with you?" She finally ask. I simply nod at her and when I turned back at her, I smiled. I walked towards the door and before I opened the door, I ask her.

"Can you join me in my walk there?" I opened the door and closed it by casting spells. I didn't wait for her, knowing she will follow me. I marched towards the great hall, robes billowing behind me and knowing someone was following me. I saw her in the corner of my eyes, still fascinating her surroundings.

"First time here at Hogwarts?" I asked not looking at her.

"Yes. What do you teach her? I still can't think of you being a teacher here." She laugh and I frowned.

"I can't see what's funny about that. I teach potion here." She stopped laughing and smiled at me.

"Its just not in your style. Potions? I see."

"Are you sure you don't remember anything?"

"Crystal clear."

"What is your job before you...died?"

"I'm a nurse. So how's life here?"

"Everythings fine." After that, we reached the great hall in silence. I stopped before I open the doors and looked at her.

"Are you ready?"

"Yes." With that, I opened the door and walked inside.
