harem in avn's basically means you can end up with all the LI's you want or only certain ones, the forums rules on harem means the MC can end up at the end of the vn with 3 or more LI's. theres also partial harem, not an actual tag here, means you can end up in a harem but including some LI's will automatically exclude other LI's.
Ah, gotcha. I would probably say partial harem probably is more in line with what I envision being possible.
Right now the characters I have a lot of scenes for (not included in the current build) are
Talia -Memory specialist/therapist
Skye - Tattoo artist/one night stand prior to losing memory
Annie - Neighbor, wannabe detective
Bella - Nurse, side character for now
Nyx - Skye's 'really good' non platonic friend
Some of these characters overlap naturally in the story - like Talia and Bella or Nyx and Skye - And their affections/interactions with the MC automatically play off of each other
