Im not a woman but honestly I hate harems because they have a few options.
- The mc never chooses a girl, and lives his life with all of them falling over him yet never actually goes with any of them.
- The mc becomes a player who goes with all of them, either leading them all on or getting them to all just accept the fact that he has multiple- which is completely unacceptable by my own standards.
- The mc ends up struggling and eventually picking one to go with, which is in my opinion the only acceptable harem route. Even at this, the harem either ends at this point or the girls continue trying. Even so, this usually leads to a scenario where there is much disappointment among the people who wanted a certain one to win out.
If it's not among these three options, then it's pretty rare as a story. They should cover almost everything, and none of them are great imo.
