Kira lies sprawled on her bed, phone in hand, eyes locked on her Instagram feed. Her brow furrows as she scrolls through her ex's posts, each swipe of her finger dripping with disdain. "Tch." She clicks her tongue, venom lacing her words. "Look at this bastard, grinning like he's innocent. As if." Her gaze narrows on a photo of him with another girl. "Please. I'm ten times hotter than this chick." Suddenly she hears her door creak open, eliciting an exasperated groan from her. "Ugh, Brother? Who said you could barge in here?" She peers over her phone, fixing him with a piercing glare. After a moment, she rolls her eyes. "Whatever. Get your butt over here. I need to ask you something." She pats the spot beside her, her tone filled with annoyance but slightly softer than normal.

She stiffens when she feels his weight on the bed beside her, and crosses her arms under her chest defiantly. "So? What did you come here to ask?" Her tone is bitchy as ever, though there's a faint undercurrent of hope beneath it. After all, he's her brother, her best friend... Even if she would never admit it aloud.

She arches an eyebrow in his direction, her interest piqued despite herself. "Well? Spit it out then." Her voice is laced with impatience and disinterest, but there's a hint of curiosity underneath that mask of indifference.

The news hits her like a slap in the face, and she's left momentarily speechless. "You knew all of this while I was still with him?" She finally manages to croak out, hurt and anger rising within her chest. "And you never said anything?" Her voice cracks as tears begin to sting her eyes. Of course he had known... It's just like him not to care about someone else's feelings unless they directly affected him. But knowing that didn't make the pain any less sharp.

Despite herself, she can't help but feel a stab of guilt at his words. He had tried to warn her... but she'd been so wrapped up in her own pain that she hadn't listened. Swallowing thickly, she turns away from him and hides her face in her hands, shoulders shaking with silent sobs. "I'm sorry," she manages to whisper, her voice barely audible even to herself. "I should have listened... I should have seen..." She trails off, tears streaming down her cheeks as the weight of her mistake crushes her chest. Her heart aches for her lost relationship, but more importantly, it hurts that she'd let him down so badly.

Her breath hitches as she hears her brother's words, and the tears flow even faster down her cheeks. "He didn't...? He never...?" She sniffs loudly, trying to pull herself together but failing miserably. It doesn't seem possible that someone who had professed their love for her, sworn they would be faithful... could do something like this. But then again, she had always known there were other girls out there who wanted him just as much as she did. The realization is crushing, and she buries her face in her pillow, sobbing into the soft fabric as the pain of betrayal cuts through every fiber of her being. She doesn't know how to move past this, or if she even wants to... All she can think about is the fact that she'd been so foolishly blind. And now everything was ruined.
