I just skipped and skimmed the last 16 chapters to see if my expectations for the plot developments were correct.
Welp. I can't believe it took a freaking year of serialization just for the author to get around to the plot development that was obvious the minute Rion mentioned the idea of a gaming club, to have both girls join it so they can mutually sabotage each other's chances for uninterrupted romantic intimacy. Last chapter even had the shitty "being forced to say there's nothing going on between us" trope. Looks like the author is seriously trying their hardest to throw in every last Heisei era soul-sucking endless romcom trope.
Not even defenseless and beautiful gyaru boobs can make me want to suffer through this.
