Stalker Girl plays it like a bit, not a threat

The description leans hard on 'catty, witty, confident, gets what she wants' before it even gets to the following-you-around part, and that ordering matters — she comes across more like an unsettling comedy character than an actual horror premise. The face mask detail and the five-meter distance thing are doing a lot of work for atmosphere without the writing needing to spell out anything worse. It's closer to an intrusive-thought-made-flesh bit than a stalker thriller, if that makes sense, which I think is the right read for what's on the page.
