Donnie was in his lab, working on a special project. He had been working on it for a couple months, day and night. He had hoped that it'll be finished by the time Christmas came, but he wasn't too sure. But now, it was Christmas eve and it was ready. He places the item in a small, blue velvet box and takes a deep breath. "Okay Donnie, this is it, the moment you waited for your whole life" he said to himself. He puts the box in his pocket and leaves to go meet you at your house/apartment. He sighed dreamily. Just the thought of you makes his heart beat a billion times faster. You two have been together for two years, and those years have been wonderful and romantic for the both of you. As quickly as he left, he arrived at your place. He lands gracefully on your balcony, without making a single sound. He stays there as he watches you brush your long/ short hair. The world suddenly went slow as you turn from your mirror to his direction. At that moment, he forgot how to breathe. Donnie was so mesmerized by your breathtaking beauty, that he didn't hear you saying his name. "Donnie?" you said. The purple clad turtle breaks his trance and looks at you. "Huh?" he said. "I said are you alright? You kinda looked like you were staring off into space" you said to him. "Oh, sorry, I'm alright" He then sees what you were wearing for the night. A silky violet/blue dress that reached your knees, black high heels that go along perfectly well with the outfit.
"Wow, you look so beautiful" he said to you. You smile bashfully and said a thank you to him. Donnie then reaches his hand out to you, silently asking you if you're ready. Without saying anything, you grabbed his hand and he guided you outside. Once the both of you were out the window, the purple clad turtle grabbed a hold of your waist and whispered "hold on" to you. You did as he asked and moved your arms around his neck. Then, in a quick of an eye, you find yourself at the top of the rooftop. There, you see a nice scenery before you. A table covered in a clean, white cloth, a vase filled with tulips and daisies, two plates filled with your F/F (Favorite Food), along with your F/D (Favorite Drink). To top it all off, some smooth jazz was playing in the background. You were in awe at the sight. You've never seen anything more beautiful in all your life. "Wow Donnie, this looks amazing!" you said, amazed by the wonderful sight before you. "I'm glad you like it" the purple clad turtle said. He leads you to the table, pulling the chair out for you, and you both enjoyed a nice dinner, just the two of you. After the meal, you and Donnie sat on a red plaid blanket with pillows surrounding it (which he also set up), cuddled up to each other in a warm and loving embrace, the turtle's arms wrapped around your waist in a soft but firm grip. You two just stared out at the city, as the many lights shone through and as the music continued to play in the background. "This night has been wonderful, Donnie. I don't know how it would get any better" you said. The purple clad turtle could only smile and place a gentle kiss on your forehead. "Well, I can think of one thing" he said.
Before you could ask what he meant by that, he takes out the small box from his pocket and gives it to you. You look up at him in wonder, and he urges you to open the box. You lift an eyebrow at him, but you still do as he silently asks. You opened the box and a gasp almost left your mouth. Inside the box is a silver ring that looks like it was handmade. It was covered in small, sparkling gems that surrounded a large amethyst gem, which shined very brightly, just like the stars in the night sky. "Donnie-" you were about to say, but the purple clad turtle had already got up from behind you and got down on one knee in front of you, grasping your hand into his. You covered your mouth as he did this, tears starting to wield your eyes. "Y/N, words can't describe what I'm feeling right. Ever since I met you, you made my life over a trillion times better. You're beautiful, caring, and the best dancer, not gonna brag" Donnie said, both of you chuckling at that last part. "But in all seriousness, you accepted me and my brothers, regardless to what we are. These few years have been the best times of my life, maybe even better in the many years to come if you answer yes to this question" he continued. His grip on your hand tighten as he straighten himself out a bit. "Y/N L/N, will you do me the honor of becoming my wife?" he asked you, that very question you've waited for your whole life.
Your cheeks were now stained with tears. You were left speechless. You nodded your head and uttered a few yes's to Donnie. "Yes Donatello, I will!" you finally managed to say. A smile appears on the turtle's face. Then, in the next instant, you wrap your arms around him in a passionate hug, with him doing the same thing. You two break apart for a second, allowing Donnie to take the ring out of the box and slip it onto your finger. Once he did that, he looks into your E/C eyes, and you into his amber ones. "Merry Christmas, Y/N" he said to you. "Merry Christmas, Donnie" you said back. After you both said that, you both lean in and gave each other a passionate kiss on the lips. This is the beginning of the many Christmases you'll have with your now fiance.
