The Eight Sin: The cat sin of betrayed

Maneki backstory

12 years ago I was talking to my parents and my mom said " Kazue you are going to be crowned queen in 2 weeks'' I said to my mom" that is not fair what about me!? She looks at me , "well the oldest gets to be crowned first then you are next to don't be selfish". I was jealous and angry at the same time.  I walked around the village, I talked to one of my friends named Aki and she looked at me concerned 'Hey what's wrong?"  I sigh and took a deep breath before I talk when I looked mad "My oldest sister

made a plan I was going to disturb Kazue ceremony then I walk out of my clan territory I went to the human land when I hid my ears and tail I said to them" I want to join the holy knights" they agreed with me.2 Week Later I told them the Neko clan is planning something to kill the holy knights they were shocked when they said" ok show me the clan place" when we went to the place my ears and tail went the knights attacked killing 2,000 Neko with my little brother and my parent I saw my sister crying and freaking out I kinda felt bad when I saw my sister getting yelled at and getting blame she is running away to save herself.  When my leader said" we're good now let's get back now" My stomach turned I felt like murder and I betrayed my clan I wanted to cry but I couldn't. 2 days.

Later when I saw my sister getting arrested she gave me an angry look. I felt like a jerk when Meliodas came. He took her in and created Eight Deadly sins. Still should I apologize or should I not? Anyways she was going to be crown queen and I want to be king. I am definitely going to apologize to her when I see her in the future. 

Present time ( because why not this is my favorite part of the story but Maneki P.O.V.)

I was walking with Gilthunder and the others when I heard Kazue's voice. She was talking and I said to her in shock " Kazue, how are you alive? I thought you died?". When I looked at Kazue she looked mad. I could tell because her tail is straight.  The others looked confused Gilthunder said, " dude what are you saying how can you understand her and do you know her" he said" well I can speak cat to I am definitely not a Neko I am human for sure and I know her from my past " I said to myself' damn they might suspect that I'm not human' . When I saw Kazue hugging gowther I was getting irritated but also confused are they dating or close friends . I tried to talk to her in human language and she hissed at me then she started talking to me. I made a sad face because I felt bad after what I did to our clan. After Kazue stopped talking she ignored me. But I want to be friends again and show her that I changed.
