Okay so the payoff is definitely coming. Arai has spent a while setting up Aya’s jealousy and how she feels like she’s just a friend and has no right to keep Mitsuki to herself BUT this new arc is probably gonna tackle that and their relationship is hopefully going to get some nice development
At this rate, Mitsuki might get called to the principal office and be told to tone her natural perfect 10 charisma stat down, less she sets the entire school ablaze :P
I really want to see this chapter from Mitsuki's perspective lol. "Why is Aya growling? Why did that freshman just jump out of a bush and through the window? Why are they fighting now???"
