Yall are over reacting, although you do have a point. The character dynamics are kinda fucky. Feels like the author kindof only cares about shrine girl, and there are a lot of way waaay better manga that explored her archetype.
@cnd I left NON a comment about the concept of a man dating a bisexual girls couple, and she gave it a like. So I hope we can at least get a 3+ way relationship. Although technically polyamoury alone wouldn't be that big of an evolution because that's still an open relationship.
Its funny how with only a few exceptions Katagiri-san in the actualy manga itself looks relatively thin and avg, while katagiri-san in the artwork panels just has an absolute dumpster truck of an ass.
