Author's note: I apologise for the delay in this update. I am not abandoning this story and will try to update regularly now. Life was very busy during last few months and I was not getting any time to update. Less action in this chapter as writing after some gap. Will bring more action in next few chapters.

Please review even if you don't like my work :)

Harry grimaced at the text she was reading, "It talks about breaking of own soul. Why would anyone want to do that? Its inhuman. "

She came to Salazar's library to wait for Tom, and started reading the book lying on the table.

"Dear I told you this book is about very dark magic. You won't like what you read in this." Slytherin founder replied while scratching his chin.

Harry shook her head, "But Salazar why would anyone break their own soul?"

Salazar took a deep breath and explained to her about protecting the fragment of soul to defy death and attain immortality. Harry who was listening to him open mouthed looked back at the book once he finished.

She turned the page and read the title of the next chapter - Horcrux.

She stared at that word and tried to recall where she read it before. She ran her finger lightly on the printed word, and said "Horcrux"

Salazar just nodded as she read the title of the next chapter, then explained "Horcrux is the object in which the fragment of soul is hidden. Usually it's a very powerful magic object. Creating Horcrux gives one the ability to anchor one's own soul to earth if the body is destroyed."

She did not look up at Salazar as he explained, and kept on staring at that word. She finally remembered reading that term on Tom's black diary written in Parseltongue. That exploded so many questions in her mind.

Does Tom want to create a Horcrux? She knew Voldemort attained immortality. Was this his secret? Was that diary...

She stopped and looked up at Salazar feeling really worried. "Tom wants to create a Horcrux?"

Salazar stared at her shocked, "What?"

She pointed towards the title of the chapter, "He had this term written in his diary."

Slytherin founder shook his head, "I don't know. He never discussed anything about Horcrux with me. He was reading that book to know more about soul mates."

She gazed at him confused, " Soul mates?"

Salazar frowned, "He didn't tell you?"

She shook her head, " Tell me what?"

Salazar rubbed his eyes, "Oh dear. I think he must be looking for a right time or maybe he forgot."

She looked frustrated," But Salazar.. Tom has the best memory. He doesn't forget. What is it about soul mate?"

Salazar stared at her, then sighed and replied, "You and Tom are soul mates."

She looked confused, " Huh? "

He then explained to her about soul mates the same way he explained to Tom few week back.

Harry frowned slightly as she heard the whole thing. She heard the term soul mate on Muggle television few times, but she did not understand the whole meaning of it till now. So she was parselmouth as she and Tom were soul mates? Was this the reason for all those similarities?

She remembered herself asking the question about being a Parselmouth like Dark Lord to Dumbledore, and he said that Voldemort left some of his powers when he tried to kill baby Harry.

Left some of his powers?

She started staring at the book in her hand again and touched the word Horcrux.

Left some power or ... Maybe some fragment of himself?

She closed her eyes as she remembered few visions she had of Voldemort, the ability of Parseltongue which no one in the Potter family ever had, same wand core, the pain in the scar.. she stopped

She had not felt any pain in current era. Even when Tom was angry or touched her scar she did not feel any pain. And technically Voldemort had not tried to kill baby Harry yet. That means she can't have his soul fragment.

Tom brought peace and completeness in her life. He was her better half, the one who balanced and completed her.

That means it was not what she thought it was... she smiled and gazed back at Slytherin founder, who was staring at her with a very worried expression.

It was not some dark magic, it was pure Love. And that type of love and attraction she felt towards Tom was only possible if - "We are soulmates", she said that loudly and started laughing in happiness.

Her laughter made Salazar even more worried, "Harry dear?"

Just then library door opened and Tom walked in, he stopped as he saw Harry laughing.

As soon as she saw him, she stood up and ran towards him, then threw her arms around him and kissed him. "Welcome back Tom."

Tom started smiling at her enthusiasm, "I thought you were angry with me."

She stared up him with a slight frown, " Angry? Why?"

Tom raised his eyebrows, "Last evening in the kitchen?"

"Oh" She shook her head as she completely forgot about their argument last evening.

"I forgot about that. You are forgiven." She said as she took his hand and started walking towards Salazar's portrait.

Tom chuckled, "Forgiven? But I never apologised, and I will punish Barns for what he did. "

She stopped and met his gaze, "Tch.. Lets not talk about him."

Then sitting back on the chair where she was sitting earlier, she asked, " So how was your meeting at Gringotts?"

Tom sat down on the edge of the table and picked up the book about soul magic he left earlier. He frowned at the chapter Horcrux then stared at Salazar, "You let her read this. "

Harry frowned at Tom, while Salazar chuckled and said, "I told her the subject is too dark for her but she was curious."

Tom shook his head as he closed the book, and threw it back on the table. He took Harry's hand then smiled at her, "Meeting went great. We have more than enough gold for our future."

Slytherin founder grinned, "I am so happy for both of you. But your claim on my vault also means that. "

Tom nodded and gazed at at Salazar, "I am now Lord Slytherin. "

Harry immediately stood up, "Lord?"

Tom nodded, she knew how much that title meant for him. She hugged him again, "I am so happy for you."

"And thanks for loving me. It was because of you that I was able to enter Slytherin vault and claim it."

She frowned, "You had to enter a vault to claim it?"

It was Salazar who answered, " Yes, only the heir in love would have been able to enter there successfully. "

She stared at Salazar and asked," And if unsuccessful?"

Slytherin founder shook his head, "Then he might have lost his magical abilities."

Tom nodded, " Yes Goblins told me about that."

He met his fiance's gaze, as he tookout one rolled up sheet and quill he brought from Gringotts. "Harry I have this contract. You just need to sign this with... "

She took the quill and the contract from his hand, and signed it before he could even finish. She felt a slight stinging feeling on the back of her hand, then realised that the quill actually used her blood for signature instead of ink. She forwarded the contract to Tom, "Here. I signed it. By the way... what is this contract about?"

Tom met Salazar's gaze then glared at her, "Harry you should never sign a contract like this. You should have let me complete then signed it. What if I made you sign on something you don't want or agree? "

She tilted her head slightly, " But Tom I trust you more than myself. If you wanted me to sign it then it must be something good. "

He could not help but smile at her reply. Her trust meant alot to him. He put the contract back in his pocket, "Its our marriage contract."

She grinned, "See its good. So the contract for our marriage." She nodded and added, "What's a marriage contract?"

Salazar started laughing.

Tom shook his head and replied, "We'll get married once you are of age and I am you legal guardian from now on. I will take care of your needs and health. You are now my responsibility Harry. "

She smiled at him and he smiled back, both kept on staring at each other. Then Tom realised something.

"Harry?"

"Yeah"

"Why are you here in your nightclothes? And where are your shoes? "

"Oh that? " She gave a nervous laugh.

Tom raised his eyebrows.

She bit her lip then said, "I had a nightmare and wanted to see you, so I ran straight here and decided to wait for you."

In her dream she saw herself standing alone without Tom in future and that scared her more than anything.

Tom just stared at her, then said, " So you were roaming around in the castle at night without any warm clothes? Without shoes? I hope you are carrying your wand. "

She replied in a very low voice, " I left that in my dorm. I did not realise till I reach here. " She thought he would scold her for this and looked away from him.

Tom did not say anything but stared at her as she looked towards the wall without meeting gaze.

He sighed and removed his scarf then wrapped that around her neck. Then tranforming his gloves into shoes of her sizes, he placed those on floor so she could wear them. He also put warming charm on her clothes. Then touched her cheek to check her temperature.

She started blushing as she was overwhelmed by his consideration. No one ever cared this much for her.

He met her gaze and said, "Harry you are my responsibility now. Make sure you carry your wand with you all the time. And you will not roam around in the castle at night. "

She nodded as he kissed the back of her hand.

He stared at the portrait of his ancestor, who was smiling at the display of affection by his heir. "See you later Salazar. I think she missed her sleep like me. "

Salazar nodded, "I will see you in the evening. Let me know the details about that meeting with Goblins."

"You won't believe it. He sent me this ridiculous bracelet for Christmas. No gold. No precious stones. Just thread with butterfly dangling here. "

"Cecilia said that Tom got her ... "

Harry covered her ears with pillow trying to block the high pitch voices of her stupid dorm mates, who seemed to have returned few minutes back.

There goes the peace of her dorm. Now it would be their continuous giggling and chatting.

She returned to her dorm early morning to get some sleep. Tom's scarf was still wrapped around her, as she loved his scent closeby when she slept.

"Oh Merlin. I am so jealous of her. Isn't he a dream boyfriend? She is so lucky.. "

She won't be getting any sleep now, taking a deep breath she sat up and moved the curtains.

Linda smirked, "Oh hi Harry. Sorry we woke you up. Good morning.. I mean afternoon."

Harry frowned, as Jenny added, "Yeah sorry about that. But why are you still on bed? It's so late. "

Linda nodded, "Yeah Harry. You didn't sleep last night?"

At this Jenny mouth fell open and she asked, " Oh that means you were with someone. "

Before Harry could reply Linda asked, "Who is the loser? "

Jenny giggled and added "Lin I think it must be that idiot Jason from Griffindor. Sabrina told me he got a new secret girlfriend. These two make... "

"Shut up both of you." Harry cut them before they could make anymore of their stupid speculations.

She rubbed her eyes then stood up and moved towards the bathroom. On the door she stopped and looked back at them. She wanted to clear few things "You wanted to know where I was?"

They nodded.

She smiled, "I was with Tom last night. You know that fifth year Slytherin Prefect. He is my boyfriend."

"Boyfriend? " both of them said at the same time.

" Tch.. Oh .. not boyfriend.. but I should say my fiance Tom. You see he asked me to marry him and I said yes. And I will be moving in with him this summer. Isn't this great? " She gave a false giggle mimicking them.

Then she looked at them seriously, as both of them had their mouth opened in shock.

"And tell that Connolly to stop spreading false rumours about Tom else I'll tell everyone who the new secret girlfriend of that idiot Jason of Griffindor really is. "

With that she walked into the bathroom and shut the door.
