where did you read it?
On reddit, a user was reading the raws and they read up to 18 chapters and there wasn't much progress between Alessia and Fleria. And more screen time interacting with 2 dudes/male leads.
Reddit dicussion "Is this legit or bait?":

I also skimmed through the chapters up to the last one, chapter 24. And it doesn't look too good. It looked like your typical yuri bait.... I hope not but it seems like Fleria might just really admire/worship Alessia platonically.
Here's the raws to the webtoon (all the chapters are free):

that sucks ass damn
I've read online that it's a bait. They're platonic gal pals and they each end up with their own male lead.
