A romantic and successful achievement
Changeling Hive 9:00pm
In the Changeling Hive, the changelings of the Changeling Hive were all seen having a stroll around their Kingdom happily and peacefully like they always do in their daily lives in the beautiful Kingdom of theirs. The species have also established bonds and friendship with each other and with ponies too thanks to Ponyville's friendship princess Twilight Sparkle educating them about the significance and components of Friendship and why they should always treat each other with dignity and respect no matter where they are from.
In a bedroom in the Changeling Hive, King Thorax of the Changeling Hive was seen looking at his reflection with the help of his mirror stand, he was wearing a tuxedo while trying to adjust his bow tie. The reason behind this is due to the Changeling King himself receiving a letter from the love of his life Twilight Sparkle herself saying that she offered him to attend the Canterlot fireworks show to celebrate her success in spreading friendship across Equestria. When the changeling saw her invitation, he couldn't decline, because he is her special somepony after all, he couldn't disappoint her.
"Alright so, I just need to adjust this upwards a little." Thorax said as he adjusted his green bow tie upwards "Okay I'm done." He said looking at his reflection with a pleasant smile.
"Time to head to Canterlot, hopefully Pharynx would do well in watching over my subjects when I'm gone." He said. After that, the changeling King turned around and walked to the door of his bedroom. Once he got to it, he gripped onto the door handle and pulled it open. Then, he stepped out of his bedroom, closing the door behind him in the process. Finally, he began to make his way to the front gates of the Hive so that he could fly to Canterlot and meet up with Twilight and her friends.
Canterlot 9:30pm
In the garden area of Canterlot castle, a lot of ponies were seen gathered in the large garden area of the castle in preparation for the celebration of Twilight's successful contribution to them all in friendship. She was seen standing by the entrance of the garden waiting for her special somepony Thorax to arrive.
"Where are you Thorax?" Twilight asked in a slightly dejected tone.
"What are you doing Twilight?"
Twilight turned around to see her mentor Celestia walking up to her.
"Oh hello Celestia." Twilight said in a depressed tone which Celestia noticed.
"What's wrong?" She asked "Today is the day of celebration of your success in spreading friendship across Equestria, you can't be sad." She told her.
"I know but, I'm just feeling a bit left out without Thorax here." She told her.
Celestia was a bit shocked to hear this, she didn't know that her student was in love with the Changeling King Thorax, all she knew was that the changelings also established friendship and bonds with each other after some lessons from her. At the same time, she does feel bad due to her depression on Thorax not arriving. Then, on cue, a voice was heard.
"Hey Twilight!"
Both ponies looked forward and saw the Changeling King himself Thorax walking towards the entrance of the garden area of Canterlot castle while wearing a tuxedo. The sight has made Twilight smile brightly.
"Thorax!" Twilight said running towards him in a rapid pace that surprised Celestia. When the friendship princess got to Thorax she jumped towards him, the changeling caught her in a hug but, he eventually lost balance and fell on the ground with Twilight on top of him.
"You came!"
"Of course I did, what kind of special somepony would I be if I do not attend your special event?" Thorax asked.
Twilight then pulled her head up and gave him a kiss to the lips which made Thorax blush in return. A brief second later, the alicorn princess pulled away and looked down at her lover with a giggle.
"You're so sweet Thorax." Twilight said with a smile. "Anyways, want to start partying now?" She asked getting off of him.
"Sure beautiful." Thorax said standing up on his hooves.
Then, Thorax and Twilight both began to walk to the entrance of the garden area of the castle where they will start the party.
When they got in, Thorax had a small chat with the rest of Twilight Sparkle's friends known as Applejack, Rainbow Dash, Rarity, Fluttershy, and Pinkie pie who asked him how he was doing and be replied with a simple 'I'm fine'. Then, Celestia tipped on a microphone.
"Welcome my subjects to the party dedicated to Twilight's success in spreading magic and friendship." Celestia said and the ponies cheered "Without further ado, let's commence the party!" She exclaimed.
During the party, ponies talked to each other about how their lives are going, how amazing this party is, how good of a job Twilight Sparkle is doing her work and many more. But, after half and hour through the party, Celestia moved onto the next phase of the party that Twilight requested for her to do, and it is a dance between her and her special somepony Thorax. However, the changeling King does not know of this due to Twilight keeping it as a secret and a special surprise for him.
Twilight then walked up to the stage set up in the middle of the garden with the help of Celestia. When Rainbow Dash noticed this, she flew to Thorax before lifting him up with her hooves, making him drop his cup in the process.
"Whoa! What are you doing Rainbow Dash?" Thorax asked.
"Ah nothing, just bringing you to your special somepony." She replied simply as she hovered her way to the dance floor of the garden. When she got to it, she gently dropped Thorax onto it and flew back to her friends.
"Geez, the nerves of that mare." Thorax said in a slightly aggravated tone as he stood up from the floor.
"Thorax, do you like this dance that I requested Celestia to arrange for us?" Twilight asked holding his hooves.
"It is nice but, I didn't remember you mentioning anything about a dance in the letter that you sent to me." Thorax said in a slight perplexed tone.
"Sorry, I wanted to keep it a secret for you because, this is a surprise dance between me and you Thorax." She told him. "And I also picked a suitable song for us to dance to and sing for you. It describes the both of us perfectly and can help us relax." She finished which made Thorax surprised.
"Alright my subjects, you will now witness the lovely dance between Thorax and Twilight Sparkle who have established a loving bond with each other, under the request of her." Celestia said which made the ponies excited "Now, without further ado, Vinyl, hit it please." Celestia said.
Vinyl nodded and inserted a disc on the spindle, after that she placed the stylus on the disc and a song began to play.

Twilight: For the power of the sea. And the bright and shining stars. A drop of breaking dawn. All of Equestria's in symphony. On the touch of a hoof. Even just a tiny soul. A sky so wide and bright. You can open all the doors. You're overthinking everything. It makes you all confused. A lonely heart and soul. Right in front of us both. Don't ever let your sight decide. Who to trust and to believe. Never let the fear in your heart. Give you a reason to start a fight. One day you'll start to see. Gets better everyday. You'll feel it in your heart. Can hear it in your voice. Can see it in your eyes. It's all what you become. It's all of the proof you got here. So ride along the wind. And go through heavy rain. Let the light fall into you. Believe a brighter life. So open up your eyes. Try to listen to the sound. Even through the darkest night. Believe a brighter life. You'll be surprised to find the colours bright and free. The sound of energy. The world is full of life. So take my hand, we'll go. A step to reach the goal. We'll sing it out and loud. And tell it to Equestria.
Thorax was extremely amazed and touched by the singing of his lover Twilight Sparkle, this song really perfectly describes the two of them and is actually making him relaxed just like she said it would. Twilight on the other hoof was amazed by how good Thorax was with dancing with her, he sure does know how to impress a mare. Then, she started to sing again.
Twilight: It's such a lovely place to be. Standing here beside you. And right now as I open my eyes. I see the world I'm dreaming about. I may not have the words to tell you. But I know you understand. Walking to the same direction. So I know you feel what I feel. One day you'll start to see. The darkness in the sky. Will turn to brighter days. Believing in your heart. Someday you'll realize. The journey that you have. Will make you rise and fall. Just hold onto your dreams. So ride along the wind. And go through heavy rain. Let the light fall into you. Believe a brighter life. So open up your eyes. Try to listen to the sound. Even through the darkest night. Believe a brighter life. You'll be surprised to find. The colours bright and free. The sound of energy. The world is full of life. So take my hoof, we'll go. A step to reach a goal. We'll sing it out an loud. And tell it to Equestria.
Once the song has ended the ponies all erupted into applause from the beautiful singing of Twilight Sparkle as well as their dance. The friendship princess sung beautifully, while the changeling King danced with her in an adroit and beautiful way.
"That was a nice song you sang to me Twilight." Thorax said with a smile.
"Thanks Thory." Twilight said, and Thorax blushed from the cute nickname "And you danced with me pretty well." She told him.
"Thanks Twinkles." He said and Twilight giggled from the cute nickname given to her by him "Anything for you." He said.
Then, the two royals stared at each other with blushes on their cheeks until they inched their faces closer to each other and kissed each other in the lips, this has made everypony squeal and scream happily for the couple.
A brief second later, fireworks were blasted into the sky, some formed hearts, some formed flowers and many more. Celestia was so proud of her student finding love with Thorax, so we're her friends.
"I love you Thorax." Cooed Twilight.
"I love you too Twilight." Cooed Thorax.
The couple nuzzled each other affectionately while the fireworks exploded in the night sky. Both the Changeling King and the Friendship Princess have achieved their goals in not only spreading and maintaining friendship but, finding love with each other.
