@kaminomikan Impossible with this kind of setting and with how honest Rokudo is. And currently, they are not in love with him for real, they are just under the spell's influence.
On a side note, I don't understand why you guys like harem. No woman would ever want to share her man. Polygamy used to be legal in my country and it was a mess. Wives and children sabotaged each other to gain the husband's favor. My great-grandmother died a lonely death. Harem manga are fine when the MC choose one at the end. Harem ending is really shitty and unrealistic.
