I haven't read Pyramid Game so I'm not sure if the characters or the relationship dynamics match 1:1 but these are all great GLs for newcomers to the genre:

As for your question, top and bottom are most commonly used to differentiate the sex positions in yuri, although some people can also refer to the top as "tachi" and bottom as "neko", too. There's also a lot of yuris where they switch positions.
Thank you
I started watching pyramid game and read the webtoon. (It's not tagged yuri/shoujo ai I know) looking for yuri enthusiasts and experts here. I've never been into yuri but this just peeked my interest to reading something dynamics like this.(I like it were the top is shy/timid/depressed and the bottom is like normal? I dunno how to describe it not the loud/noisy dumb type but kinda like the mc for the pyramid game? Kinda like a rational and intelligent, smart and capable character(dont confuse it with the attitude obssessed with grades smartass kinda character)
Any yuri/shoujo ai recommendations like this kinda trope? Preferably nothing explicit, kissing is fine. But Im new to this and dont wanna scare myself to the yuri scenes.
Question: If Seme is for top and Uke for bottom I wonder what the titles are for yuri?
