Serena's POV:
I was sitting on the bench of the butterfly estate as Tanjiro, Zenitsu & Inosuke were training a lot. Even, Nezuko was watching them too.

"Serena? Should you training with them?" Aoi asked as she was really confused of me. "No... I don't feel like training today" I said as Aoi was surprised of this. She was prepared to say something until Tanjiro came up to me. She then,  leaves me and Tanjiro alone.

"Serena! Why are you not training with us? Is there something wrong?" Tanjiro asked as he was really worried of me. "There's nothing wrong, Tanjiro. Everything is fine" I said as I gave him a warm smile. He then nodded at me as he was prepared to go back to training but, I stopped him for a second.

"Tanjiro. I want to tell you something" I said as Tanjiro give me the look of confusion but, he then sat next to me. "What is it, Serena? What do you want to tell me?" Tanjiro asked as I pulled out the silver crystal in front of him. His eyes were widen in amazement of the silver crystal.

"Tanjiro... do you remember, I cured Master Kagaya?" I asked him as he nodded at me. "Y-Yes, Serena. Why?" Tanjiro asked as he was really confused of me.

"The silver crystal could do more than cure people, Tsnjiro. My mother sacrifice to save me and my friends from the evil forces even, our memories are a erase" I said as I was still looking at the silver crystal. "Also, the silver crystal can destroy us & the evil forces too. My mother did this to protect me and my friends from evil forces..." I said as Tanjiro had tears in his eyes.

"I didn't know... you went through this even, your friends got involved because your kingdom was destroyed by evil forces..." Tanjiro said to himself as feel so sorry for me. "Tanjiro, It's not your fault. This happens in circumstances even... my soul is connected to the silver crystal too" I said as Tanjiro's eyes were widen in shocked of, what he heard.

"W-What?! Your soul is connected to the silver crystal?! Why?!" Tanjiro asked as I looked back at him. "It's because it's my responsibility to keep the silver crystal safe from the evil forces. So, the silver crystal is connected to my soul. Even, I can still control the silver crystal too" I said to him as Tanjiro was amazed of this. I then put the silver crystal away to make sure it was safe.

"I need to check on, Kyojuro & the others now. I'll see you later, Tanjiro" And with that, I leave the butterfly estate and walk to the flame estate too.

/Time Skip/

I made it to the flame estate as I was about to knock on the door until the door was open and, revealing Senjuro.

"Oh! Hi, Serena! I'm really happy your here now!" Senjuro said as he gave me a hug. I then hug back as I was really confused. "Hey, Senjuro. Where's your father? Even, your brother too?" I asked him as I looked around the flame estate.

"My brother should be back by now. Also, father is in the back garden too. He's getting a lot fresh air because he was inside the house so long" Senjuro said as he was really happy. That's a good thing for Shinjuro, he's getting healthy. Then both of us heard someone behind us, when we turned around. It was Kyojuro and he was holding flowers in his arm too. When Kyojuro saw me, his smile was widen as he came up to me.

"Serena-chan! My flame! I'm glad you came!" Kyojuro said as I was confused of the flowers in his arm. "It's good to see you too, Kyojuro. What's with the flowers? Is it for someone you care for?" I said as Senjuro was watching us still.

"This is for you, Serena" Kyojuro said as he gave the flowers to me. I was shock of this, I was still staring at the flowers as Kyojuro was smiling. "We can spend time together and, get to know each other. I really, what to know you, Serena! So, we can make a family together too" Kyojuro said in happily tone. I looked down on the floor as I was trying to say somehting to him but... he was making it hard for me.

"Serena-chan? Are you okay, my flame?" Kyojuro asked as he got worried for me. Then I break the silence as tears started to form in my eyes. "No... I'm sorry, Kyojuro... We can be together.." I said as I gave the flowers back to him. Kyojuro looked confused, when he looked at me until he saw tears falling from my eyes.

"I'm so sorry Kyojuro but... I think, we should stay separated from each other" I said as I started to run away from him. I can't let anyone came near me anymore. I'm so sorry Kyojuro... I can't let you get in the way of the plan.
