Harry got a message to appear at the bank. She may not know a hell of a lot about the wizarding world but she knew better then to ignore a Gringotts summons. So she grabbed her things and summoned the night bus making her way to the bank.

She was not expecting Oliver woods to already be sitting there, and from the looks of it being extremely grumpy. When she walked in, he looked up at her and gave her a very weak smile. "Miss Potter have a seat," the goblin ordered as she quickly did so. "Your family has an outstanding marriage contract."

That was an extremely blunt way to put it but it took her a moment to realize what he had said. "Oh shit," she said before she could stop herself. Even muggle raised she knew what that meant.

Oliver nodded, "With my family," he added.

She couldn't even figure out what she thought about that. Married to Oliver just seemed like something she couldn't even think of at the moment. Marriage was so permanent and she couldn't understand how this happened. She was panicking and she knew it but she couldn't stop it. "What...why would my parents do that," she demanded. "Why would our parents do that?"

"Great great great great grandparents," the goblin corrected. "Congratulations, you are married."

He handed them the marriage contracts and left the room. His job was finished so he left them to deal with it. Harry picked up the life changing document hesitantly. Seeing it there in front of them made it feel even more unbelievable. "According to this on the eldest coming of age we are officially married." A second later she came to a realization, "Oh merlin you turned 17 a week ago."

Oliver nodded having already known that much, "yeah I did."

It took a moment for Harry to speak, she was too horrified to even think about what was just revealed. "You can't marry at 13. It's illegal," she faltered slightly looking to him hopeful, "isn't it?"

He only wished that her age was enough to make this go away. "Technically, love everything about this is illegal," Oliver stated but he knew enough to know that it being illegal did not stop it from being possible, "want to get out of here and talk privately, I got a room at the Cauldron. Gringotts always makes me nervous."

She nodded agreeing fully as she followed him out of Gringotts and into the Leaky Cauldron. She made sure to keep her head down and her hair covering her face and especially her scar. The last thing she wanted was to be mobbed once again. Once they were inside he silenced the room so no one could overhear which seemed to happen so often with the young famous witch.

Once they were inside, Harry spoke up. "Oliver, how is this legal?"

He had to take a steadying breath before speaking or else he knew he would not be able to get it out. "It's a line contract that never was expected to be enacted," Oliver said sitting down. He could see that, knowing their family history but the fact was, despite the intention behind it, it was now something that they would have to deal with the rest of their lives. "The agreement was, whenever there are two children of the lines, one male and one female, born within 5 years of each other the contract enacts and marries them on the eldest coming of age."

Harry felt sick, "So you're telling me that because we were born exactly 4 years apart we are now married. How hasn't this happened in the last three generations?"

"Line curses," Oliver stated and now she was really confused. "I keep forgetting your muggle raised. Sorry love." He went silent thinking of how to explain it. "It's simple in theory, certain family lines have curses. Malfoys were cursed with a specific appearance. All Malfoys have white blond hair and grey eyes. Other families are cursed with specifics."

"Specific what?"

Oliver decided to use the Weasley's since they would be easier to explain, "Weasley's, six sons and a daughter right?"

"Right."

"Their family was cursed with only sons," Oliver stated, "But seven is a magically powerful number. The seventh child broke the curse for that family line. Having a daughter in a son cursed line is supposed to be the most extreme blessing. Our families had line curses as well."

The Weasley's made sense. So did the Malfoys since she had seen both the father and son, they were carbon copies of each other. "Alright so how's our families cursed?"

"Your family has a few curses, the hairs one. All Potters have wild black hair."

She twirled her hair in her fingers at that smiling slightly. "I was always told I got that from my dad."

Oliver too smiled, the comment seemed so sweet, innocent and so like the younger girl. She always did take a lot of pride in some comparison with her parents, the connection. "Yes you did. Second curse for your family is only sons."

She pointed to herself wondering if he was insane, "you got the problem here."

Oliver chuckled since he had thought it very strange as well, "Yeah we do, you're a girl which doesn't fit family history. This is why I checked into your family tree. As your husband I can do that I hope you don't mind."

She didn't even have any idea where she could find one so she would have to remember to ask about that later. "I don't...what does it say."

"Your mother was squib born, her family had a curse as well. Only daughters, she was part veela," Oliver said pulling out a family tree which she looked at amazed. "From France, I am going to guess her grandmother had an accident and lost her magic. Veela are very rarely squibs but they can lose their magic if they destroy their core or do certain rituals. Sometimes a bad accident in childhood. Her mother was probably a weak squib from the looks of it and so she was born from a line who only has daughters. It looks like when you were born your parents did a line test to find out how they got a daughter."

Harry ran her fingers over her parents' name. "So my dad's line was cursed with sons, my mothers with daughters and so I am a girl because of that. Since both our lines are cursed they counteracted and I ended up a girl."

Oliver nodded, "Exactly," he said pleased that she understood. "And because of the previous contract, we are now married. The contract was supposed to just be a binding agreement, so our loyalties remained the same not an actual marriage contract, but we both fall into the category and I just had my 17th birthday."

"So I am married at 13," she added, while it was obvious she just couldn't get over that fact. She knew marriage contracts existed in both the muggle and magical worlds but it was a terrifying thought to be involved in one. It was something that she had never thought she had to worry about.

Once again, all Oliver could do was nod his head. "I am sorry Harry, I wish I could fix this for you."

She didn't really understand what he meant. He should have been worried about himself. He was the one bound to her for life. "For me what about you?"

"I'm not happy about this," Oliver said, "But I am not miserable by the thought either. Remember, I am a pureblood Harry. Old family. Contracts were always a possibility, when I was 17 of course but with someone my own age. I don't mind that person being you."

Her eyes widened slightly since she did not really know how to take that comment. He didn't mind being bound to her for life? "Us being married...what exactly does that mean?"

Oliver shrugged, that was part of the issue. She was young. In the future, it wouldn't be that big of a deal but right now she was only 13. "Right now, it makes me your legal guardian. As you're of age husband, I am your legal guardian which means you don't ever have to return to those muggles."

She grinned which he returned knowing why she was pleased by that statement, he'd be damned if he let anyone harm his young wife. "Okay, this marriage thing is looking up. Continue.'

"Then it means whatever you want it to mean. I like you Harry, being married to you is no hardship for me. It won't be anything until you are older but I would like us to be happy with this marriage."

She thought for a moment, it was Oliver. He was one of the best guys she knew. If it was anyone but him she would probably be freaking out right now but it was Oliver. "Maybe we should date," she decided shocking him. "We ignore the contract for the most part and just date. Wait you said guardian, does that mean you can sign my Hogsmead form."

Oliver couldn't help it, he had to laugh. "I will most definitely sign your form, we will need Hogsmead so we can appropriately date. So Harry Potter, would you like to be my girlfriend?"

"Hmm..." she teased, "I don't know. What would my guardian say?"

He poked her in the side laughing. She broke down and joined him. "Our lives are messed up."

"Oh yes they are," Oliver agreed but perhaps it wouldn't be as bad as it could.

"So, Harry what classes are you taking as electives,' Oliver asked curiously as they ate ice-cream. Relaxing. They had spent so long discussing what their marriage could possibly mean that they needed a switch of topic and so classes were easy enough to bring up.

She thought for a moment, "Divinations and Care."

Oliver cringed not liking the sound of that, "I'd like to advice against that. Having Trawlawnys like asking for trouble."

Harry looked surprised, "What do you mean?"

"She's a fraud who likes to predict student's deaths, it's a pointless class but Arithmacy and Runes, and even I have to admit they are useful for nearly every career."

"I'll think about it," she decided having never heard about that before. "What exactly is Arithmacy and Runes?"

"Shouldn't the professors have...they cancelled class counselling because of the attacks," he said feeling like an idiot. "Okay well let's start with Arithmacy shell we?"
