Everyone Else is a Returnee
Left out during elementary school picnic.
Left out during middle school camp.
Left out during high school trip.
I finally became a college student and what? I’m left out from the entire humanity?
Yu IlHan who protects the earth alone while everybody’s away in other worlds.
His legend starts after humanity comes back and meets the Great Cataclysm!
