A guy working as a cashier on a kombini, then there's a dungeon break and he was trapped inside a system for thousand years until he broke apart and returned to his world which had already been filled with dungeon gates and creatures?? He only has a mom I think... who was killed by the monster too. I remember this manhwa specifically because of the awesome monster designs, but I can't recall the title
