Is Everyone Else Is a Returnee Worth Reading? Review & Where to Read

Overview

God sends all of humanity to another dimension to train against an incoming monster invasion — and forgets about Yoo Ilhan, an unnoticed college student, leaving him alone on Earth for a thousand years. By the time everyone else comes back with their hard-won powers, Ilhan has had a millennium to grow into something far stronger than any of them, with nobody around to see it happen. It's a clever inversion of the usual chosen-one isekai setup: the strongest person in the story is the one who got left out, not the one who got picked.

What it does well

That premise alone earns a lot of goodwill. Instead of a tutorial-tower power-up montage, you get a genuine sense of scale from a thousand years of solitary survival, and the story leans into the dark comedy of a near-omnipotent loner who can't get anyone to notice him even when he's standing right in front of them. The action, once it kicks in, has real weight behind it — Ilhan isn't strong because a system handed him levels, he's strong because he's had a thousand years to earn it the hard way.

The absurdist streak works too. A lot of the humor comes from other characters completely failing to process how overpowered this awkward, invisible guy actually is, and the gap between what Ilhan can do and how the world treats him is a solid running joke.

Where it falls short

The catch is that Ilhan's actual behavior on the page doesn't always support the sympathetic read the premise sets up. He spends the story wanting to be seen, but the moment someone does approach him, he tends to act dismissive or prickly instead of engaging — which reads less like a believable case of long-term social atrophy and more like the story wanting to have it both ways: a lonely protagonist you feel for, and an edgy loner protagonist who gets to look cool by pushing people away. It's a real inconsistency, and it's the thing readers push back on most.

There are also some looser worldbuilding details — whether ordinary weapons work against the monsters shifts depending on the chapter — that suggest the adaptation was compressed from the novel faster than it could fully iron out. And right now, the story is on hiatus between seasons, so there's no clean stopping point to recommend it around.

Verdict

Great pitch, shakier execution — Ilhan is more compelling as a concept than he is chapter to chapter, and whether that bothers you probably depends on how much slack you're willing to give a lonely-genius lead.
