The thing that gets me is people are only complaining about Karane and Hakari, but not a word has been spared about Mei. Crenanville, who seemed one of the more moderate arguers talked alot about Rentarou remaining the axis of the harem, but Hahari is indisputably the body which Mei orbits, with Rentarō being a pleasurable side-benefit. That state of affairs did not somehow break the manga so I’m not sure the anti-polycule positions actually hold water.
overall, I’m kinda tired of seeing people complain about yuri every single time it appears, but the name-calling and defensiveness are both a particularly egregious waste of time, energy, and feelings
