What the-
Nope, the tag says shoujo not yuri

I think there are a few mangas whith multiple couples of different sexualities, but they are still tagged with the genre, and I think that's pretty reasonable since people prefer to know what they are going to read. Your Idea could be a whole new genre which I think would be really cool. Maybe in the future they are going to create something like that, like they did with the omegaverse.

I read it fast as "why not.. just yourself" and I was like: yeah that's the best gift ever ლ(´ڡ`ლ),... wait, hold on... nope I read it wrong ( ̄へ ̄)
I re-read the manhwa from the start after a long time, I'm so fucking glad I did. 1- I could understand it better, 2- I forgot how much I loved this manhwa ε=ε=(ノ≧∇≦)ノ
Honestly when i started reading the first chaps i was soooo confused and i wasnt understanding anything...then i read all the story and now i understand everything and im happy, now i love the story very much
