Hi Dev, what are the future planned tags? Harem/NTR/Sharing...
The harem route isn't a 'serious' one at the moment, it's more like a fun bonus content thing, I will give it some attention in the future and see if I can make it work with the story (no promises!). The story is mostly finished and NTR/Cheating is not part of it, if I were to add something like that, it would be half-baked and conflict with parts of the story itself, plus it would change the entire relationship dynamic.
