Jace's P.O.V:

"Clary! Come down for a second!' I yelled from my bedroom in the institute. Clary's feet rattled as she raced down the stairs and finally found me. Her eyes met mine and she could tell I was excited, so she poked a couple of kisses on my face. "Whats up?" Her green eyes were wide with wonderment. "Close your eyes and count to 560." I smiled as her jaw opened widely. "560? Can't I just use a timer?" Clary groaned. "Fine, but no peeking until 560 seconds is up." I had planned a big surprise, and 560 second was definitely not enough, but it was enough for Clary to wonder what I was up to. 

Silently in my head, I was rehearsing my plan over and over again. No one knew what I was going to do, and I wasn't quite sure either. My palms were sweaty by the end of my plan, and my heart was beating faster and faster each second. "500 seconds, 1 minute left."  I whispered to myself. Currently, I was in the weapons room looking for Clary's stele. A bright light flashed by my eye and I glanced over to my side where her stele lay. Remembering the trick Magnus taught me, I wrote something on the tip of the pen- a message Clary would always remember. "530 seconds Jace!" I heard Clary call up from downstairs. "Crap." I sputtered to myself. There was only 30 seconds left in the biggest part of my plan and if I didn't get this done, everything would be ruined. 

"I'm coming to find you!" Clary screamed in the hallway as she headed upstairs. I opened the door to the weapons room and acted like I was throwing blades. My body started getting jumpy so I knew Clary was nearby. "Aha!" Clary laughed as she finally found me. She grabbed me and kissed me right on the lips, making me less nervous. I pulled away, ready to do my plan. "Clary, I challenge you to throw a blade right in the middle of that target, are you willing to?" I hoped Clary would say yes, or else my plan would get wrecked. "Umm.. sure. Give me the blade, and watch and learn blondie." I laughed at her joke and she smiled back. Clary took the blade and threw it gracefully, spot on the target. "I'll get it." I ran over to the target and tried to pry the blade off. "Clary, its stuck." Clary came over to me and tried as well to pull it out. "Hmm, let me try to put a rune on it to see if it will come off. But where's my stele?" I pointed to the table. "I saw it there this morning, maybe you forgot to take it with you when you left yesterday." I suggested as if I had no idea how it got there, but I put it there so I actually know how it's there. Clary shook her shoulders in confusion as she snatched her stele. As she pressed down on the target, my message appeared. "What the?" Clary looked down at the message as it scrolled through. Her eyes were huge with joy as she read it.

Clary , ever since you have been with me, my whole world has been woken up. Everything about you is so perfect- from your green exciting eyes, all the way down to the tips of your tiny toes. When I first kissed you, I thought you felt nothing, unlike me. From that moment on, I knew you were the one. I don't know how else to say this but, Clary I love you. And I will love you until I die. And if there is life after that I will love you then. I will always dream of you. Whether you are making me laugh in a dream or not, I still enjoy you. When I died, there was nothing. I was nothing. Nothing to let me kiss you one more time, or nothing to let me tell you how much I love you. But then, there was the angel. I heard its voice and your voice, but I couldn't understand what you were saying. I thought it was over until the light brought me back and I saw your face. Clary, you could have ANYTHING, and I mean that. You could of made yourself a better shadowhunter, or you could have gotten a protection ward from the angel, but you asked for me. If I never met you, I would be dead. I  might have died from Valentine, or I might have died from a broken heart. So Clary, can I just ask you one thing? 

Will you marry me?   

The message ended and left Clary speechless. 

Clary's P.O.V:

Everything Jace just did was amazing. He is the most perfect man I have ever seen and I love him so much. And of course I was going to marry him! But, I have to trick him into believing I'm not. "Jace, that was amazing!" I gushed. "But, I'm just not prepared to get married." I did my best not to laugh. Jace's smile drooped and his whole face turned upset. "Clary, but I thought that you would-" I interrupted Jace. "By the angel jace, I was just kidding! Of course I'm going to marry you! You are my life and I couldn't bear without you. I love you so much and-" Jace's lips found mine. He smiled as he kissed me. I kissed him back fiercely and my whole body was instantly warm. My lips gave him one last kiss and pulled away. But then Jace hugged me, so I hugged him back tightly. My body fit exactly into Jace's- we were truly meant for each other. He broke apart from the hug, letting cold air reach me again. I let my head dangel on his shoulder for warmth, and he kissed me goodnight. "Jace, it's 8:30, we can stay up until at least 10 you know." I looked up into his beautiful golden eyes. "I know, but  you got to get some rest. The wedding is tomorrow." He smiled down at me. "Tomorrow? Seriously? No one will have time to prepare and-" Jace put his finger on my lips. "I told everybody about this a week ago and they have been preparing ever since." "How did you know I wasn't going to say no?" I questioned. "Something's you just know." Jace grabbed my hand and hauled me up. "Goodnight Clary Herondale."  He winked when he said Herondale. I kissed him one last time, hoping that the wedding would be fine. "Goodnight Jace. I love you." As I fell asleep, I heard Jace say, "I love you, Clary."  

I hope you enjoyed this one- shot! But, I'm going to do a part two, so it's more like a two-shot;) This was the proposal part, so next part will be the actually wedding.
