This is going to be based when Lucy is a member of Fairy Tail. Also she never met Natsu.

Lucy was at Sabertooth picking fights as usual. When Sting called Lucy  over to talk about a new mission. Sting said I am putting u on a job with Fairy Tails Dragon Slayer Natsu Dragneel. Your mission is to go and kill demon.I hear this job was specially assigned to u and Natsu. Natsu  will be  here  in  30 min to come get u. She said how will I find him. Sting smiled and said look for pink hair.Lucy gave him a puzzled look but then said ok.

30min later

                                                          LUCYS POV

Natsu was late so I decided to just go and meet him there. I was about to sit then saw a man with pink hair I wentup to him and said are u Natsu Dragneel. He looked up at me and said yea and u are Lucy Heart. Nice to meet u Luce. What do u need? I said we were assigned a job together. Remember? He thought for a minute and he said oh yea. Then is face dropped and said I'm so sorry I forgot. I'm just used to doing jobs by self with me and my buddy Happy but he went on a job with his friend Carla. I said its ok and walked away, but then he said u can sit by me if u want I don't bite. I decieded that I would. So I sat across from him. He looked sick and I said are u ok. Nodded and said motion sickness. I said oh. I decided to put his head in my lap. Then I realized he is really warm and before I knew it I was a sleep. I was getting shakes and when I opend my eyes I saw Natsu. At first I kicked him because I forgot it was on a job so I apologized. Then we made our way to the owner of the job.

Later. After they talk to the job request person.

Natsu POV
We just got done getting information on the job. We were walking to the woods to where the job was. I just thought what was Lucy's magic. I was about to ask when we were attacked by a monster. I was about to protect Lucy when I heard"CELESTIAL DRAGON ROAR!!!"Once I heard that I realized SHE IS THE CELESTIAL DRAGON SLAYER!!!!!I was in amazement for a moment and then I snapped out of it. That's when I started to fight then I screamed FIRE DRAGON ROAR!!! Then Lucy looked at me in amazement. I laughed. We almost beat the monster when a monster from behind Lucy and stabbed Lucy on the stomach. I ran and catches her before she feel to the ground. I screamed her name but she did'nt seem to hear me. So I picked her up and ran to town as fast as I can.

          Lucy's POV
I was smiling at Natsu I was about to say I'm a celestial dragon slayer. But then felt a sharp pain in my stomach and I fell. I saw Natsu run to me and that's all I rembember. Then I was asleep.

          Natsu's POV
I just made it to a hospital. I screamed HHHHHEEEEEEEELLLLLPPPPP!!!!!!!!!!!!A nurse came running in and said carry her to the surgery room and u must leave. I stared  her down and she said I have to go. I sat her with a like hell im leaving. She sighed and continued working. She started to sow the hole back up and that took a few hours. Then they took her a the intensive care unit and hooked her up to a oxygen mask and said she will wake up in a few days is there any one u want us to call. I said call sabertooth guild and tell them Lucy got hurt. She nodded.

A few hours later

Sabertoooth came in a said where is Lucy. I pointed and said she should be up any minute. They all ran to her and whispered they were there. Then Sting came up to me grabbed the collor of my shirt but I didn't care and said what happend I said she was stabbed by the monster. I didn't see it behind her tell it was to later. Sting said never let this happend again and walked away. 

           Lucy's POV
I was hearing what everyone was saying but I couldn't tell then it was alright. Then I heard Sting yell at Natsu. I wanted to stop them and tell Sting it wasn't his falt. I wanted so hard to move my hand but it wouldn't move tell I felt my finger move a inch. I prayed that someone say it. Then I heard silence. After a few seconds I felt a warm hand. I didn t care whose it was I was warm. So I went up and cuddled with it.Then fell back asleep.

        Natsu's POV
I saw that Luces hand move and I touched it because I didn't want her to be alone so I held it.  Sting was about to say something tell I felt her move and press her self against me and fall back asleep. Sting was amazed he hand never seen this side of her.  He just glared and went to Yunkio his girlfriend. I just stayed out because I didn't want her to wake up and the next thing I was asleep.

        Lucy's POV
I woke up and saw that I was  next to Natsu. Then I remembers that I was cuddling next to the warm person next I me. Natsu sturred and woke up and he hugged me. I blushed at first but then hugged him back and said I'm ok. He called for sabertooth. Then o rembembered they were here. The next thing that happend I was trampled by Sting,Yunkio,and Rouge.

A few hours later they all left and it was just Natsu and me. I told Natsu he can go but he wouldn't leave tell he knew I was better. Also I think he felt bad because he felt like it was his falt.  I kept telling  him it wasn't. But he stayed. I was about to go move around. Then a sharp pain came. He noticed and helped me up. I blushed and said Thank u.  He smiled. I went to bed but then a hour after I went to sleep I had to use the bathroom. I sat up and was about to stand. Once I did I fell. I freaked out and did my only instinct and screamed. Natsu heard and woke up. He saw me on the floor saw me sobbing. He asked what's wrong and y are u one the floor I told him I was going to the bathroom and then I fell. I screamed I CANT WALK!!!!He looked at me confused but then he was about to get a nurse to come but I hugged him and told him not to leave. He hugged me and said I'm not going any where. I sighed and went went to sleep in Natsu's arms. He picked me up and put me in bed. That's all I rembembered.

         Natsu's POV
I heard a thud and a scream. I woke up and saw Lucy sobbing and I asked what wrong and y are u out of bed.  She said she got out of bed to use the bathroom and she said she could walk. I stared at her confused for a minute and then it clicked. SHE COULDN'T WALK. I was about to go for help. But she held on to me and told me not to go. I stayed and she sfell asleep in my arms. So I picked her up and put her to bed and waited for her to fall  asleep. After a few minutes she was lightly snoring.  I left for a nurse. She came in to expect her and saw that there was a huge clot in her legs.
