It was a manhwa that I read a few months ago maybe even a year ago IDK it was a bl that played in a world like solo leveling (portals, hunters, etc) but it was at the beging first portals opening yk so they send military in the portals and every family had to sent out one kid. This rich family just adopted a kid to sent to military (mc) he then went and got stuck in there since time went by slower in there and the families actual son he grew up and became a s class hunter and saved mc i think. I'm lowkey not sure if what I'm saying is even true it's just what I remember.
