Build me a romantic full screen confession website that feels like a cinematic slideshow. I want it to tell a love story one screen at a time with gentle animations, photos, and short editable lines of text that I can personalize directly on the page.

It should start playing right away when I open the HTML file in a browser, work nicely on both desktop and mobile, and let me move through the story with the arrow keys. I also want a surprise at the end when I press Esc, and a small corner button to pause or play the background music. Please make it so I can easily swap in my own names, photos, and song later without needing any special setup.

Keep it simple, just plain HTML, CSS, and JavaScript, with no build step. If anything needs current browser behavior or docs checked, look it up online first.
