I just said it's a very peculiar thing for a fan to put up.
Not that I’m expecting you to know this, just pointing out that fans creating videos of their favourites couples (or “ships”), whether real or fictional, and setting them to romantic ballads, is genuinely a big thing and has been for years and years now. Any popular TV characters in a romantic storyline you can think of (and many you probably would never think of 🤣) will have loads of these created by fans and posted on YouTube, twitter, TikTok etc etc. Celebrity romances also, There are bound to be loads of tribute videos posted of Meghan and Harry too. Welcome to the wonderful world of parasocial relationships!
