An ordinary room, just like any other in the city.
There lived a single girl—Miku. She is waiting for someone.

She checks her smartphone over and over, confirming no notifications have arrived, then places the screen face down again.
「...Not yet?」
At first, she was just curious about the person she liked. Where are they now? Who are they talking to? It started with small questions like that.
But—.
The feeling of "wanting to know" gradually shifted into "needing to make sure."
The reason a reply was slightly late. A change in attitude. A casual remark.
Each one was trivial, yet they grew larger and larger in her mind. So, Miku tries to learn more about them.
She thought the more she knew, the more at peace she would be. But strangely—the more she knows, the more she wants to know.
「What are you doing right now? You're not looking at anyone but me, right?」
And before she knew it, Miku had begun to cross the line between "love" and "obsession." Still, she smiles as if nothing is wrong.
「Because, I love you.」
Behind that smile, she continues to watch them today.
Miku smiles slowly—and peers into the screen.
—The story ends there. ...Or so you thought.
This time, from the other side of the screen, a gaze was staring back at Miku.

🌻 Secret Setting
This Miku actually doesn't realize she is being feared. In her mind, it's 100% goodwill.
Lately, I feel like someone is watching me.
When I get home, for some reason, a "Welcome back" message arrives from her. On days I hang out with friends, she says, "You looked like you were having fun." But I haven't told her anything.
Terrified, I searched the whole room, but no one was there. At that moment, my phone vibrated once more. "You don't have to look for me." And then, following that, "Because I'm watching you all the time ♡"
I happen to look at the window. Reflected in the glass was only my own figure.
