The writing prompt made me think of Beyoncé's Irreplaceable more than the "even those that are truly irreplaceable" scene in season 4 so here it goes.

TRIGGER WARNING!: This oneshot talks about an abusive relationship. Although there is no description of physical harm, there are mentions of things done that are bad for someone's mental health.

Enjoy!

Allura loved the bright colours of the carnival because it reminded her of Altean flower fields. When she closed her eyes, she felt like she was back home. "Hey miss sunshine, you okay?" Shiro asked while pressing a kiss on her forehead. "Mhmm," she hummed, "just thinking about how I'm going to... How did you say it... Kick your ass at the next game." He chucked, "Is that so?"

They waited in line for their turn at the balloon and darts game. Allura was busy trying to get a better look at the prizes when Shiro saw him. "Allura," he whispered in her ear, "can I get a hug?" Allura didn't hesitate to turn around and hide her face in the crook of his neck. Shiro held her close as Lotor passed nearby. He didn't want her to see him and let that ruin her day. When Lotor's eyes noticed Allura's white hair, he took a step forward but quickly stopped when he saw who was holding her. The two men stared at each other before Lotor walked in a different direction with his entourage.

That was the only time Shiro saw him that day.

The Altean princess, not suspecting a thing, turned in Shiro's arms to face the front of the line and still have his arms around her. She didn't understand why Shiro suddenly needed a hug but he seemed to be alright now and that's all that mattered.

The sun had made way to the moon and evening breeze. They walked hand in hand towards their final ride of the day: the ferris wheel. Shiro got them a private booth and three back-to-back rides. They took their seats and Allura layed her head on her boyfriend's shoulder, her fingers were playing in the fur of her newly acquired Tottoro plushie.

"Shiro, I have to tell you something..." Allura whispered while the passengers were climbing into the other booths. "Tell me, I'll listen," Shiro replied. She smiled, he always was so good at listenig to her. "I don't think you'll like what I'm about to say."

Shiro's eyes narrowed. "Allura, if something is botherig you, you can tell me." She bit her lip and looked away. "I... when you left to use the washroom I... Lotor saw me and he came to talk to me." Shiro let go of the breath he was holding in. He wasn't happy about this at all but at lease he knew what got her worried. He Shifted their position so that his body faced hers and he could see her face. She looked exhausted. "It's been two years, Shiro, two years and he still tries to get me back, say that I'm making a mistake, that..."

"...You'll never get someone like me Allura. Come on, dump that loser and get back with a real man. "

"I said no, Lotor. Now leave me alone!"

"You can never replace me: I'm irreplaceable."

And in that moment, something clicked in Allura's mind. She looked at Lotor dead in the eyes. "Oh Lotor, you are so right..."

"Finally!"

"You are irreplaceable. I wouldn't want another person like you in my life ever again. One was more than anyone should ever have to handle. You were mean, manipulative and flat out abusive. Claiming to love me then sleeping with other girls behind my back. Claiming to want me but never showing up to any of the things that mattered to me. Claiming that I meant the world to you and yet you treated me like total trash! Why would I want to replace you with another mediocre version of you? No... I did an upgrade. I got everything I deserved and more. Why would I want to replace you when I can just forget about you all together and get someone who is actually good to me?" A crowd started to gather. Lotor realized that he wasn't going to get her back, grabbed his drink and left.

"I'm sorry I didn't say anything but... the day was going so smoothly and... by the time you came back he was long gone..."

"Those damn washroom lineups," Shiro whispered while rubbing his temples. He took Allura's hands in his. "Thank you for telling me and...don't ever hesitate to talk to me, okay?" She nodded.

"I also know that you were trying to stop me from seeing him back when you asked me to hug you," she confessed. Damn she's good, Shiro thought. His defeated look made a small laugh escape from her lips. "Shiro," she said while siting on his lap and hugging him, "I can't thank you enough for all you do for me. But don't hurt yourself trying to think about how this could have been avoided: it... It was about time I told him off once and for all."

Shiro looked at Allura, moving a strand of hair away from her face. She didn't seem upset anymore, she was... at peace.

"Are you sure you're okay?" He asked. She nodded.

"I'm exactly where I want to be," she replied.

Looking in her eyes for her permission, he kissed her, a constant reminder of his love for her, a simple gesture he would repeat every chance he got to be with her, an unspoken promise of his faithfulness and admiration to the one he would never let go of.

Tadaa!

I feel like my stories can never do justice to what I'm imagining in my head, practice makes perfect I guess :P

Let me know what you think!
