I don’t know one where a girl lives in a bl world, but one with a boy http://www.mangago.zone/read-manga/zettai_bl_ni_naru_sekai_vs_zettai_bl_ni_naritakunai_otoko/
There is also “once upon a fairy tale” where a girl gets isekaied in a normal novel (not BL) in a male body, but it turns out pretty gay hehe (the male lead is into the mc). It’s on web toon or ta pas (free)
Check out surviving as a maid. The plot is good but it has really slow update (▰˘◡˘▰)
Is there a manga/hua/hwa where a girl was isekaid into or lived in a world of bl? Just curious. If there is, tell me I wanna read itヾ(❀╹◡╹)ﾉ~
