While the story setting seems unique and interesting, with hidden organisations and what not, that's about the only thing of interest. The characters are all, without exception, broken and so superficial that it gets annoying when they just interact. I still don't understand how the harem tag comes into play here, since the mc is probably one of the most unlikeable characters if seen so far. He couldn't even care for his mom, who somehow managed to pay the bills for them to not end up on the street. the annoying part about that is that this not caring about anyone and not having emotions for anyone is emphasised repeatedly for no reason at all. Interesting world building with (imo) terrible character design. Good luck
