Please no, harems are unrealistic, and 99% authors will make up cringe reasons for their creation, such as the MC having "too much stamina for one woman", or other such reasons.
One of the most enjoyable Star Wars fanfics I've read! MC is actually intelligent with his system, and his interactions with the rest of the characters draws you in. A lot of area to cover, and we are just getting started, eagerly looking forward to the future!
