Harem realities. You have to be unbelievably intuitive. You have to see a spark of trouble brewing before it catches fire. This will still happen occasionally anyway. There's zero room for insecurity or weak behavior. If the girls start a spat, you stop it, period. Have to have insight and compassion. To know what they are thinking sometimes before them. Not an easy thing to do. However, it won't work any other way. They will never take lead in making a harem. 3sum maybe
