I think for SH it is not only that same writer, but also she was expected to be the msot popular romance option(Well she is actually lmao). I still belive that Laezel would fit much better than SH for example. SH with all her character development and talk(family,farm, kids etc.) doesn't really fit. As were said before, you could randomly skip all those encounters like Halsin/Drows while romancing here and you would never get even a thought that she might be open to this kind of stuff.
