A/N: Lmao, I legit came with this idea while I was watching Brothers conflict
What if Urie had a little sister (check media) and she would join the Quinx squad a little bit later than the others?
Anyways, enjoy this weird oneshot
-----------------------------------
Author POV
It's been one year since you have become a member of the Quinx squad and half a year since you and Urie started forming a couple
You knew that he could be really cold, more than usual and he would keep a lot of things to himself
You respected his privacy, until one night...
You were about to fall asleep when Urie's phone's screen lightened the whole room, making you groan frustrated
"Who the fuck..." you thought, getting up
He was sleeping and the thought of looking through his phone crossed your mind
"What the heck, [Y/N]" you sighed, heading back to bed. "I trust him, he wouldn't do such things... he wouldn't... right?"
You finally decided to look who sent him that message as such a late hour as your heart was beating faster
You took his phone and went on the halls, opening it
Kanna: I'm so excited! I can't wait to see you tomorrow!💖
"Who... who the fuck is Kanna...?" You thought as you could feel your heart just skipped a beat
You wanted to know more about this 'Kanna', but he had a password, so you were left confused and only with that message
"You'll see tomorrow, Kuki" you thought, going back to the room you two shared

Time skip
Morning
And the morning started pretty great...
Yeah, with yelling and doors being violently closed
"They're fighting, aren't they?" Asked Shirazu, groaning frustrated as Mutsuki just sighed
"They're so loud" the eyepatched male whined
"Okay, I had enough!" Snapped Saiko who just came into the living. "I woke up because of them and I was sleeping so well!"
"I can't believe you're looking through my stuff without my permission!" Urie shouted from upstairs as Shirazu just facepalmed
"I can't believe you're fucking cheating on me!" You shouted back as Saiko groaned frustrated in a pillow
"Who the fuck said I'm cheating on you?!" Urie retorted as Mutsuki just sighed
"Then who the fuck is this Kanna bitch?!"
And there was a little moment of silence as Saiko, Shirazu and Mutsuki thought you stopped fighting, when...
"Why aren't you saying anything?!" You broke the silence as the three teenagers sighed in unison. "Because it's true, right?!"
"Holy fuck, woman! It's not true!" Urie retorted as he was coming into the living room
"Then why aren't you saying anything?! Is it that hard to give me a damn answer?!" You shouted, following him
"Thanks for bringing your fight here, yay" sarcastically said Saiko
"Oh, shut up!" You and Urie said in sync
"Are you going to tell me or not?" You asked, calming down a little. "You have one minute, Urie Kuki, to tell me who the fuck is this Kanna bitch--"
"U-um" said a female's voice. "I think I am"
You turned your head to the source of the voice when you noticed a young woman of average height that had the same hair color as your boyfriend
"Everyone..." started Sasaki. "This is Kanna Urie-chan, our squad's newest member and..."
"My little sister" completed Urie who just sighed frustrated
You blinked fast a few times, looking at the purple haired girl, then at your purple haired boyfriend
"Oh" you muttered, looking at the ground as you blushed in embarrassment. "Maybe if you told me, this wouldn't have happened" you said, running upstairs
"Great, his only family left and I made a great fucking first impression" you thought, sighing
"[Y/N], wait" Urie called after you when a familiar hand grabbed him by the wrist
"Onii-san!" Kanna called as Urie looked at her from the corner of his eyes. "Why do you always have to be so stubborn? Look at what you just have done, you've upset your girlfriend!"
Urie just sighed for the umpteenth time today as Kanna pulled him in a hug
"I missed you, Nii-san"
"Yeah, I missed you too, Kanna"
"Oh, wow, you've been in this house for five minutes and I already like you more than your brother" said Saiko as Urie just glared daggers at her
"I agree" Shirazu said, giving Kanna a smug smirk
"Shirazu, don't you even dare look at my sister" said Urie in a threatening tone as Shirazu looked away
.

Kanna's first day in the Chateau went pretty great...
A lot of information about everyone was shared as they were getting to know each other better
Saiko said a few times that Kanna is totally Urie's opposite, saying that she's nothing like him, but in a good way
And you... you refused to do all of this...
After you straight called her a bitch, you've locked yourself up in your room filling reports, scrolling on your Instagram, reading or God knows what only to kill some time
Kanna was worried as hell because she was thinking that she hurt you in some way, until she decided to come to your door
"[Y/N]-chan..." Kanna's voice was heard from the other side as you were peacefully reading. "Can I come in?"
"I'm so embarrassed..." you muttered, closing your eyes. "Leave me alone... please..."
"I just want to talk..." she sighed
Hesitantly, you opened the door for her as she looked a little surprised at your sudden change of heart
Without thinking too much about it, she threw her hands behind your neck, pulling you closer in a hug as you had a shocked look plastered on your face
"Thank you..." she said out of the blue
"For what?" You whispered, looking at her in disbelief when she pulled you away. "I called you something I shouldn't, I--"
"I know you didn't mean to" she cut, looking in your eyes. "I can't thank you enough that you stay by my brother's side, love him, care for him and be his only family when I was gone... It means a lot to me to finally meet the person that changed him"
"To finally meet the person that changed him?" You repeated after Kanna as she just shook her head up and down
"You don't know? Kuki speaks very highly of you! He wouldn't stop talking about you every time we met. He was like: [Y/N] this, [Y/N] that" she continued, imitating Urie's voice as you giggled at her impersonation. "Of course I wanted to know who this [Y/N] person is since he won't stop talking about her"
"I think it's enough, Kanna" Urie's deep voice was heard in the room as Kanna froze in place
"I'm so sorry..." you apologized as Kanna looked at you with a bright smile plastered on her face
"You don't have to be sorry if my brother is an idiot" said Kanna as Urie glared daggers at her. "Besides, we're family now, right?"
Both you and Urie blushed madly as she just looked a little confused at the two of you
"Not yet?" She asked one more time as you covered your face in embarrassment and Urie just sighed
