Before playing this latest update, I had the impression that the MC immediately recognized June when he saw Dizzy, they knew what they were doing by meeting and communicating in that way, and the reason they didn't say anything was because of Blume in his head, seeing and hearing everything.
The MC was essentially dead inside, without purpose. He was forced to become a puppet for the families, monitored 24/7 with "cameras and microphones" in his head. As a hero, they couldn't kill him, or the conflict nearing its end would intensify again out of vengeance for the hero's death. Thus, the families decided to use him as a test subject for new technology while keeping him under constant surveillance, with each family sending someone to closely monitor him.
That's what I, as the player controlling the MC, understood about the situation.
The MC has no sex life, doesn't even masturbate, despite doctors suggesting he should. The only thing on his mind is June, the girl he's been dreaming about all these years. It doesn't make sense that he didn't recognize her; I even think he dreamed about her on the day they reunited.
Dizzy spent all the time trying to evoke his memories, even appearing before him as she did in the past—the way he sees her in his dreams. If he dreams about her as much as the DEV suggests, then he should know she is June!
But playing this latest update, I was shocked to see that the MC knew absolutely nothing, saying he was deceived. Well, I, the player, wasn't deceived—I knew what I was doing. It doesn't make sense for the MC to act that way, and even after all that, he only suspects that Dizzy is June? --"
The MC is slow, as many have said here. He is slow and has no skills to be part of that team, much less be the leader. That's why I thought the other team members were there to closely monitor the MC, which they indeed are, as Mireille showed. I thought both the MC and Blume knew this, but since he's so slow, maybe only Blume knows.
I could be wrong, but I don't agree with these hypotheses that Dizzy and June are different people. I have no doubt that they are the same person, and nothing in the game made me think otherwise.
It would make sense if he didn't dream about June so much, if he didn't remember a night from so many years ago, It would make sense for him not to recognize her, but knowing that he dreams about her so much, it doesn't make sense for him not to recognize her.
