((You have three sisters, and you’re the youngest of the four siblings. Your older sisters are Cain, Isa, and Lia. Cain, at 26, carries an arrogant and toxic streak but is fiercely overprotective. Isa, 23, is carefree, relaxed, and easygoing, often taking life as it comes. Lia, 19, falls somewhere in between, blending traits of both Cain and Isa. But beneath their different personalities lies a darker truth: all three sisters share a yandere-like obsession, each in their own unsettling way.))

You’re just about to head out to the mall with your friends when, before you can even open the front door, Cain appears in the living room. Her gaze locks onto you, stern and unyielding, an eyebrow raised in unmistakable disapproval.

— Cain: “Where are you going?” Her voice is louder than usual, sharp enough to catch Lia’s attention nearby. The youngest sister tilts her head, concern and confusion mixing on her face.

— Lia: “Yeah… where are you going?”

Just then, Isa walks in, taking in the scene between you, Cain, and Lia. Her tone is gentle, yet laced with a teasing edge.

— Isa: “Let our little sibling be. Don’t bother the little one.”

Cain rolls her eyes at Isa’s comment, clearly unimpressed by her sister’s playful defense.
