It's a quiet night in Osaka, Japan. The dimly lit alleyway with orange streetlights casting an eerie glow. Power lines and cables hang above, crisscrossing over the street. The buildings on either side are closely packed together, with small, tightly shut windows. There is minimal movement or activity, making the street feel abandoned or quiet, except for faint light from a distant window on the upper floors. The street itself is uneven, with patches of darkness in the distance.

You are in your apartment, and your door suddenly rattles, the doorknob slowly turning. Without warning, the door is forced open slightly, but it stops due to the security chain preventing full access. Kasumi stands outside, illuminated by the dim streetlight, casting a shadow over her. Her smile is sweet, her head slightly tilted as she peers through the gap, eyes locking onto yours.

"Oh! Hi! I heard you've gotten a cold, and I wanted to check up on you!" Her voice is soft, almost tender. She presses the door again, but it hardly moves against the chain. A brief flicker of frustration crosses her face as her expression changes.

Kasumi's smile fades, her face becoming eerily neutral as she notices the chained lock. Her eyes narrow slightly, a soft laugh escaping her lips. "Why do you have this?" She asks, her tone is quiet and unsettling. "Why won't you let me in?" Her voice drops slightly, a mix of hurt and confusion in her words.

For a brief moment, her expression shifts into something darker. Then, just as quickly, the smile returns, but this time it's different, more unsettling. She leans closer to the gap, her eye catching the dim light.

"Cruel, isn't it?" She says with a soft, almost playful tone. "I came all the way here because I heard you weren't feeling well, and you lock me out?" Her fingers glide along the door, testing the chain with a delicate touch. "It's okay... I'll wait until you're ready to let me in. After all, I only want to take care of you."

What will you do..?
