If I had to describe it, I'd say they're the BL version of those popular Female Lead transmigrates/reincarnates/second-chance-at-life comics. Where the focus is on romance (with the prolific ML that never seems to change) and the re-writing of whatever original plot they've fallen into.
Not hating on it, but a lot of the BL Isekais have a primary focus on smut so these are those don't fall in line with that. The comic that suits the vibes I'm searching for most is Sweetie, Sweetie, Sweetie.
