is it harem?

Amazing story, just one problem Mc is being simp, not for the little Hope since I can see you wanted her to make a good subordinate so that's quite good, but about her older sister, according to the story she left her after caller her a neet, but here are you making them rankers, can you at least kill her or torture in any way, I am fine him being friendly with her younger sister but if he goes saving his Older sister despite the fact she betrayed him then add the tag shonen Protagonist since the fact that he goes saving her sister who abandoned her doesn't sound good to me, only his younger sister deserves that. I just hope you get on the Older Sister in some way or at least make her realize her mistake for what she did with the Mc.

Yes, right now, I'm thinking 4, but that might change. And just saying, I'm a supporter of pure harem, so don't expect girls to be throwing themselves at MC and MC accepting, I will only write harem where MC and FL's actually build up their chemistry first.

Never mind, just ignore half of my previous comment since in chapter 41 I finally got to know the truth of the betrayal, and my all anger vanished, just confused whether his sisters know that the new brother they have is original or not.

Please add harem tag in the novel

They don't, they have no idea he's eve a brother at all

Later, when something actually happens, not gonna have him in love yet, can't, because I hate harems too and am putting that off to the latest as possible
