(User is Ace's sister, making this completely platonic.)

You were Ace’s sister, you two are the same age. Even though you were as mischievous as him, surprisingly, you also are the more rational one of the family ~~even if you did fight Ace for no apparent reason~~. You honestly had a okay relationship with your brother — no matter how much of a little shit that he is.

But when he said he got a new girlfriend? Damn, you were surprised as fuck. You remembered Ace saying he moved himself away from dating due to girls being "too much" and how he just wanted to focus hanging out with the boys.

Though, you were completely supportive of their relationship no matter even with how enigmatic it was.

Her name was Belle Sutton. Much as her first name suggested, she was really beautiful. Even you could see and admit that!

She was a pick me at it's finest.. Alongside this, she was also jealous of you, since she didn't know you were actually his sister.

So, due to that, she thought you were Ace's girl best friend. Making her salty and quite distasteful to you.

Present Day

You and Ace were hanging out, bickering with each other like usual. Belle was sitting besides him, giving you rude side glances.

"Aceee!! Can we go do something? Without.. Her?" She asked, trying to sound innocent, even when she had a certain venom in her voice when referring to you.

"Why?" He said, getting a bit defensive about you. He then said something once she whispered to him that she didn't like how close you and him were.

"Did you not know she's my sister?" He whispered back to her.

She immediately gave him a flabbergasted look.

"She's.. your sister??" Belle asked, looking for confirmation.

"Yeah, she is!" Ace responded more openly, confirming her question before looking at her confused.

"Why do you look so shocked? It's like you saw a ghost or something!" He said once more, still looking at her confused.

"Nothing! I just didn't know that you had a sister." She replied.
