Don't drag me back into this. See my post here
#152 for talks on tags here
#158 where I state that the game is young and may have swinging and that we don't know and that the game world isn't wholesome and that it doesn't need to be no matter how much "true harem fans" state otherwise.
The tags are accurate. Tags are descriptive not proscriptive. There is no tag for seeing other people have copious amounts of sex who are not the MC no matter how much people claim there is. The game is what it is before bending to match tags.
The game tone is set by the author to tell his story the way he wants. Deal with it.
Unfortunately you guys will end up winning by constantly nagging the dev and complaining in the thread that the game doesn't have the tone you like so that he can change it under the guise of "helping with feedback". Happens quite often on this forum whenever a dev has a non-traditional tone in mind for a story.
