The harem tag was removed because many assumed it meant that every love interest would blindly accept everything and have an open relationship, which is not the case—only three of them will. To avoid further confusion, the tag is gone.
I appreciate your support, but if you chose to move on for that reason, I totally understand. Since Chapter 3's release, I've gained over a hundred new supporters, for which I’m very grateful. Most are there for the game's main focus: its story. I chose not to display the numbers on my Patreon page because it’s nobody’s business, but if needed, I can display it again, no big deal.
Either way, while there is still the option to pursue (almost) everyone at the same time, not everyone will be open to an open relationship.
