Honestly it's really tough to give feedback on an idea that's this simple. With good writing skills and craft, someone could take this concept and make it excellently hilarious, or creepy, or emotionally impactful. Or it could written to be extremely boring. I can't really give any feedback without knowing what tone/plot/anything you're going for, and seeing a significant portion of a draft to see if you've pulled off an interesting take on the subject. Rule of thumb: Any author can make any idea engaging if they're passionate about it themselves. Just write the ideas that excite you personally.
