So is this like that self-fulfilling prophecy? You don't do something (or do something) to avoid a specific thing from happening ... And because of that, it happens.
I mean Mitsuki is being a bit of garbo in this situation. It's not like she's not aware of Aya's affection towards her "guy" side. So what was the plan to just lead her along till a situation like this would happen anyway in the future? Where it comes out by accident. More than disappointing the other girl seems like someone was being a coward.
Buuut it's fine. As in, I dig it, cause it is a somewhat unique situation, and while it pictures (at least for me) Mitsuki in a bit of bad light, I can understand it. She better make up for it and Aya better not just accept some bs and go with it as if nothing bad ever happened.
FWIW, it feels pretty close to how the average teenager might react, to me at least. Especially a somewhat socially awkward one like Mitsuki, who's probably used to making up excuses to avoid things. She's just not well equipped to deal with the whole situation and she's reacting on instinct at this point, like a shy teenager would.
I think a really important part here is that she’s not just shy, but still working to accept who she is at a really fundamental level. High school is awkward and unpleasant enough when you’re not struggling with your sexuality. It adds another level of stress when you have feelings for someone but you’re scared to express them and out yourself in doing so.
I have a lot of empathy for Mitsuki, it’s an extremely scary and vulnerable position to find yourself in. As much as I remember how much being closeted really sucked, sometimes it really did seem easier than opening up to someone and facing the potential consequences. They’re obviously both queer, so I’m looking forward to seeing them figure it all out, hopefully together.
