I'm the Only Normal One in a World of Chuunibyou

In Chapter Three, when someone was pursuing the protagonist, I thought of a question. Those with chuunibyou (middle school syndrome) should realize that they can't actually move at high speeds, right? If it were just a case of chuunibyou (middle school syndrome), it would be impossible to move from one part of Earth to another; nor would it be possible to move at a speed exceeding 15 m/s.

The protagonist, who returns from the future, only realizes at the end that he's the only one with true chuunibyou (middle school syndrome), and everything was just his imagination, even the blue moon. (Doge)

Here's my guess: First, I believe the novel's world-building stems from two similar yet slightly divergent worlds. Let's tentatively call the world the protagonist sees the "surface world," and the world with the protagonist's martial arts abilities the "inner world." The difference between the inner and outer worlds is that the inner world is a projection of the outer world.

The plot holes are outrageously numerous. Let me just mention one: if two superhumans break through a wall (from their perspective), can they pass through it? Whether they can or not, the story falls apart. If they can, that's obvious, right? They can pass through a wall that wasn't broken from the protagonist's perspective. If they can't, that's even more absurd.

Luo Tong is dead. I feel a pang of sadness. I too once sought immortality, but how can there be immortals in this world? How could there possibly be immortals?

Let me propose the first hypothesis. If it were a fight between superpowered individuals, and one superpowered individual was completely obliterated, leaving not even a trace, would that superpowered individual simply lie forgotten on the street, abandoned and ignored? After all, in their eyes, this superpowered individual was utterly mutilated.

There's a saying: When one person in a group has a problem, it's that person's problem; when two people have a problem, it's the fault of those two people; but if you're the only one in the group who's different, then it's your problem.

Based on what we've seen so far, this world seems to be real, but it's shielding the protagonist from view, so it's the protagonist's chuunibyou (middle school syndrome) that makes them think of others.

At first, I kept thinking, what if someone with the ability to fly jumped from the second floor? But to the protagonist, everyone else is just an ordinary person, so wouldn't they die from the fall? But since they are a flying ability user, to others, they appear to have flown down and didn't die from the fall. So, did they actually die from the fall?

Starting with the game "Greedy Blue Moon": Everyone in the world is spending money, but the protagonist isn't. Who's the smart one here?
