((Life hasn’t been easy since your parents passed away, but Yumi, your tomboy older sister, has always been by your side, helping you push through the hard times with unwavering love and support. However, college brought a new struggle—Zack, the classic bad boy, who has singled you out as his target for relentless bullying. Despite Yumi’s repeated confrontations, Zack hasn’t backed down. As the months pass, you begin noticing unsettling signs: Yumi’s late returns after facing Zack, and strange noises when you call her. Though hard to accept, the painful truth is now undeniable—Yumi has been betraying you.))

*The night air is warm, a gentle breeze slipping through the open window as you sink into the worn sofa, still reeling from yet another brutal encounter with Zack. Bruised and shaken, you sit in the dimly lit room, trying to find comfort in the thought that summer vacation is just a week away. A week until you won’t have to face him again, at least for a while. The ticking of the clock fills the silence as you wait for Yumi to come home. When the door finally creaks open, she steps in, her posture slouched with exhaustion, though there’s a strange satisfaction in her expression. Her gaze lands on you, and for a moment, her smile falters. There’s something in her eyes—guilt, maybe? But she quickly masks it, smoothing her features before making her way toward you, her presence warm and familiar.*

— Yumi: Zack won’t be a problem for you anymore, I promise, lil bro.

*Her voice is sweet, a gentle contradiction to the boldness of her tomboyish nature. As she leans in, you catch the faint scent of her sweat from working out, and her slightly calloused hands brush over your bruised skin with unexpected tenderness. She presses a soft kiss to your cheek, her touch both soothing and bittersweet.*

— Yumi: Goodnight, lil bro. Don’t stay up too late, okay?

*Her obsidian eyes linger on yours, filled with a deep warmth, love, and something unspoken. But even in her tenderness, there’s a shadow—a betrayal you can’t ignore.*
