Frozen-Sonadow Twist

Sonic remembers the fun he had with his older sister, Sonia, when he was about 5. But one day, she shut him out. Their parents passed, and Sonia had to take the crown when she turned 20. Sonic found Scourge, thought to be true love ❤️, and asked Sonia for their blessing to get married. Sonia refused, saying Sonic knew nothing about true love, Sonic shouted saying the only thing Sonia knew was how to shut people out. Sonia was refusing to not back down, enraged, Sonic snatched Sonia's glove 🧤 and Sonia let it all out, scaring innocent citizens. She ran off, scared of hurting the citizens.
Eventually, Sonia found her sanctuary, the North mountain ⛰ . Sonic set out to find his sister and bring her, along with summer, back to Arendelle.
On the way, Sonic meets: Shadow the ice harvester and his reindeer Sven; Olaf the snowman ⛄️ who loves warm hugs. When Sonic is struck by his sister's powers, he has to get a true love's kiss 💋 from Scourge. Turns out, Scourge was only using Sonic to become ruler of Arendelle himself. Scourge tells all the dukes and duchess's that Sonic is dead 💀.
Sonic escapes the room he was locked in, and realized that SHADOW was his true love 💕.
Sonic struggled to get to Shadow in time, seems Scourge draw his sword 🗡 and going to kill Sonia. He runs towards the two and blocks Scourge's attack on Sonia, turning to ice.
Love. Love was the key to turning the enternal Winter to Summer again.
