"Mimi-san, you're so good with words. But it's already too late. No matter what you say, I've made up my mind. No matter how much I'm hated, I'll do everything I can so I can be with you." Yuu said darkly, his iris glaring down at her.

His expression and tone was another reminder to Nao that he was no longer human and that her dearest childhood friend was long gone. He was now replaced by a monster that could not be controlled by anyone.

All demons are different from each other. Nao could not help but compare Yuu from Muzan who would atleast try to mimic human emotions despite being an emotionless killing machine.

Perhaps it was due to the fact that Muzan was able to blend perfectly in human society and has learned human behaviour over his long years of living.

He was cruel, manipulative and knew how to pretend like a saint to make others work for him.

Yuu was different. He had a self centered way of thinking with only one goal in mind. In the thousands of years he was alive as a demon, he never cared for world dominance or supreme power, yet he was obsessed with overcoming the regrets of the past.

While many demons think themselves to be perfect, the reality was that they were living in a delusion filled with false promises of dreams and power.

Nao could never convince Yuu to change his mind. As a demon, his way of thinking had already been cemented in the last one thousand years. A few simple words from a mortal could not change his decision.

"You don't love me, Yuu."

"How dare you question my-"

"You simply regret your past."

Nao could only be blunt this time. Or nothing would go through.

"We were never in equal standing. You always questioned our status. I was a rich merchant's daughter and you were the nth child of a poor family. Was it okay for us to be friends? Am I worthy? You would ask yourselves these questions."

Nao sighed.

"You kept questioning the authenticity of our friendship. In the end, it only meant that you never saw me as an equal but as a dream."

"That isn't true. Stop talking as if you know everything. You don't know the truth."

"Tell me the truth, Yuu. Was it the truth?"

"That bastard killed me!" Yuu roared, his veins nearly bulging from his white skin, claw and fangs elongated as he looked more like a monster than a human.

Nao flinched.

"He killed me! Was it wrong of me to pursue you?! I did nothing wrong! Just because of his noble status, he could do whatever he wants and kill people as he please! I can't forgive him. I won't ever forgive him! And I won't forget that you chose him over me, that cruel bastard with no sense of respect for human life. I've become a monster because of him! I lost my humanity because of his actions!"

"I'll never forgive him!"

"I lost my heart because of him."

"I died before my time! I died before I could prove anything! I died and became an ugly demon! The only way I could be at peace is when I see his dismantled body infront of me!"

"Yuu..."

"I don't need your pity. One thousand years ago, you chose him and one thousand years later, your decision remains the same. But what can I do? I can't give up. What did I endure everything for if I would simply give up on my revenge? My human death would go to waste. I can't even remember my face anymore or what I looked like."

"I've forgotten many things but I will never forget the hatred I feel for that man. You will hate me until the end of time, Mimi-san. But before that, I will kill him. I will end his life and dream and destroy everything he has. The same way he destroyed me."

Nao covered her mouth in shock.

"You really don't love me. In your eyes, I'm a tool for revenge. That is what this is all about?"

Yuu chuckled and shook his head. He caressed Nao's face very gently.

"I do love you, Mimi-san. My love for you brought me ruin and had me killed. But I still very much love you."

'He haa truly gone crazy.'

"You've lost your humanity. How can you love? How can you hate?"

"Are demons not allowed to love or hate? That bastard still fell for you and kept looking for you even though a thousand years have passed. And he hates humans."

Yuu placed his hands on Nao's shoulders.

"I hate that you love him and I hate that he killed my human self. So I will kill him, Mimi-san. I will destroy him."

He wrapped his arms around Nao. "I have you which means I have something he cherishes."

"And he'll suffer because he'll never see you again. Not in this life or the next."

"You are cruel, Yuu."

"I know. If I was kind, I would have long died as a demon. If I'm not cruel, how would I make you stay with me or how can I avenge myself? I need to be cruel to fulfill my goals."

"Let me see my brother." Nao begged. "Just one last time."

"Impossible. You won't escape."

Nao shook her head. "I'm tired of talking about you and Muzan. I cannot justify both of your deeds. Both of you are cruel and selfish. But for one last time, I want to see my brother. He's dying. I can tell from our last meeting that he doesn't have long."

"You have a lot of regrets, Yuu. But so do I and if I'm going to live the rest of my life with you, let me see him one last time before he disappears forever. This is the only thing you can do for me. After this, I won't ask for anything else. Do whatever you wish."

Yuu just smiled. What other false promises was he going to hear? "Why would I grant you this?"

Nao's lips curled upwards, eyes reflecting a weary soul. "Because it is my only regret. I want to apologize to my brother. When that is all said and done...."

Nao touched his hand, cupping them together and without looking away, told him in a cold manner.

"Let us die together. "
