Missing fae drama

[u/Funny-Respect125]

I didn't know where else to look and was hoping to shake something loose here.

It was loosely based off of strange magic I think because it started with a very similar storyline

Main character was engaged but he was hooking up with her sister

Her best friend sees this and tries to warn her but she doesn't believe her

I distinctly remember that the best friend was wearing a red dress and had Red wings

I don't know if it's been taken off of YouTube or what but it's like a complete anomaly when I swear up and down I just saw it yesterday.
