@Sinjito I doubt this will be harem. Harem tag in manga is unreliable nowadays. Do you know Nisekoi? MC only has one girlfriend and the other females are purely just friends and yet it has harem tag since chapter 1 and still didn't removed to this day.
You don't count having female friends as harem. If having female friends is the same as having harem, then you, me and all males in the world each have their own harem by now.
