You should try "I'm in love with the villianess. Its also a fantasy isekai story about royalty. Except the mc is wooing one of the female characters from the start. I think the chemistry is different from this one, but the structure/genre of the story is very similar.
"The guy she wad interested in wasnt a guy at all" or (green yuri) is also a very good beginner yuri.

I dont even touch YURI in my life but this supposedly straight manhwa got me second guessing if I am missing out something amazing. Can someone recommend me a good YURI that feels like this? The tension, slow burn, not too insane for someone noob to Yuri???
