It is forbidden to fall in love with the person you're protecting when you're a knight. It's worse when that person happens to be a princess. A knights duty is to protect the princess from all harm. Jude Heartfilia asked the knight Erza Scarlet, from Fairy Tail, to protect his daughter for a month while he was away. He never knew that his daughter would fall in love with the woman that was there to protect her.

…...

Everyone in Fairy Tail was talking about the man who walked into their guild. He had a serious look on his face and was dressed in a suit. A girl who looked like she was at least sixteen stood behind him. She had long blonde hair and looked annoyed. She was wearing an elegant dress. The two had to be rich people. Master Makarov jumped off the counter that he was sitting on and walked over to the people.

"Hello Mr. Heartfilia. Is this your daughter that will be staying with Erza?"

"Yes. This is Lucy. I would like to leave very soon, so do you mind bringing her to Erza?"

Makarov nodded his head and smiled. "Of course!"

Jude turned to his daughter. "I will be back in a month to pick you up Lucy. Behave yourself and remember you are a Heartfilia."

"Yes father." Lucy said as Jude walked out of the guild leaving Lucy with Makarov. Makarov turned towards Lucy.

"So Lucy would you like to meet Erza now?"

She nodded her head and smiled. "Yes sir. Thank you." Makarov decided to let Erza teach Lucy how to relax. She did not need to be so formal. Lucy stared at the ground. She was still smiling, but he could see the loneliness in her eyes. They walked over to the bar where a girl with white hair was talking to another girl with red hair.

"Yo! Mira! Erza! This is Lucy Heartfilia. She is the girl who will be staying with Erza."

The girl with white hair was Mira and the other girl was Erza. Mira smiled at Lucy and held her hand out. "Hello Lucy. I'm Mirajane but you can just call me Mira. You can come to me when you need something."

Lucy shook both Mira and Erza's hands. "Thank you Mira and nice to meet you both."

"Lucy would you like to go to my place so you can get comfortable?"

"If you don't mind, I would love to." Lucy said looking down at her feet. Erza nodded and told Lucy to follow her. When they were out of the guild, Erza turned to Lucy.

"You can relax you know. Everyone at Fairy Tail is very easy going."

"Are you really a knight? I see that you're wearing armor."

"I'm a knight mage yes. You don't need to worry, I can protect you Lucy."

"Thank you Miss Scarlet."

Erza started walking again. "Call me Erza."

"But that is not proper for a girl like me."

"I told you to relax. You don't need to be so formal and proper here in Magnolia."

Lucy nodded and decided to look at her surroundings. Erza walked ahead of Lucy and waved at people passing by. Lucy felt like such an outsider. She looked towards the ground.

'I hate you father.' Lucy was so engrossed in her thoughts that she didn't notice Erza stop. She ran into Erza.

"I'm sorry!" Lucy said as she bowed her head and closed her eyes tight.

"It's fine. We're here." Erza said as she opened the door for Lucy. She allowed Lucy to walk in before shutting the door. Lucy looked around the room and sighed. Erza noticed that she wasn't as tense as she had been when she had arrived at the guild. "So Lucy what would you like to do?"

"Would it be okay if I wrote some more of my novel?"

"You write?"

"Yes. I love writing."

"You can sit at that desk over there." Erza said as she pointed at the desk in the corner of the room. Lucy nodded and walked over to it. She sat down and pulled out some papers from her bag. Lucy got right to work.

'So she likes to write.' Erza grabbed a book from her bookshelf and sat down to read. It was quiet in the room except for the sound of Lucy's pen scribbling on paper and the turning of pages from Erza.

...

"So Natsu did you see that girl that left with Erza? She seems so...so uptight."

"Yeah."

Gray sighed and leaned against one of the tables by the bar. "Why do you think she is here?"

"How should I know?"

"I'm just asking flame for brains."

"What did you say ice princess?" Natsu glared at Gray and then all hell broke loose in the guild. The boys started throwing punches and flipping tables over. People ran to escape the fight. Mira stepped around people to serve drinks and Cana yelled at everyone for being so loud. Both boys were kicked into a wall as Erza made her way into the guild.

"Hey Erza!"

"Stop fighting."

"Yes ma'am!"

"Uh where is Lucy?" Mira asked.

"She is right behind me." Erza turned and allowed Lucy to step up beside her.

"Hi."

"Hi Lucy!"

"Mira right?"

"Yes and I see you changed."

Lucy was now wearing a skirt and tank top. "Yeah. I really don't like that dress, but my father wants me to be what he wants."

"Well you can be whatever you want here."

"I heard you guys can do magic."

"Oh yes we have some wonderful wizards!" Mira said cheerfully. She turned towards Natsu and Gray. "Natsu can use fire magic and Gray can use ice. Oh you probably don't know who is who."

"I saw them when they were fighting. Natsu has pink hair correct?" Lucy asked.

"Yes he does." Mira said happily. Lucy looked around the guild and saw that everyone was staring at her. "So Erza, what are you guys doing at the guild? I thought you were going to go home."

"Well I wanted to let the master know that I am going to be showing Lucy around town tomorrow so I wasn't going to be at the guild. Can you let him know?"

"Sure thing Erza and have fun! I hope you have a great stay in Magnolia Lucy!"

Erza and Lucy waved goodbye to Mira and walked out of the guild. Lucy smiled as she looked up at the sky. Stars were starting to come out. Erza looked at her and tried to figure out why she was smiling. She decided to keep walking. If Lucy was happy, she could let it be. That girl seemed like she needed something to make her smile even if it was for a short time. Once they were in Erza's home, they started to get ready for bed. Erza let Lucy have the bed and she took the couch. Lucy had said it was fine and she could have the couch, but Erza wouldn't listen. Lucy laid in the bed staring at the ceiling.

'This is going to be a long month...but I like these people.' She turned on her side while smiling and fell asleep. Erza was on the couch thinking to herself.

'Lucy has a look in her eyes...I just can't figure out what it is. All I know is I want to make sure she enjoys her time with me.' Erza smiled as she drifted off.
