I shouldn't have enrolled

"How about a university where classes are held in the Tower of Babel?"
Ban Yu-won possesses the ability to not only interpret unfamiliar languages, but also to see and acquire 'concepts' from objects he observes. Since childhood, Yu-won has displayed extraordinary abilities. His grandfather tells him, "Our family descends from ancestors who built the Tower of Babel, leading people with the power to enable [communication] among all. With your inherited ancestral power, you should be able to find the lost Tower of Babel."
Though he thought it was an incredulous story, Yu-won is suddenly summoned to an unknown dimensional academy while awaiting his university acceptance results. There, he witnesses the legendary Tower of Babel he had only heard about in stories. Yu-won enrolls in the academy with mixed feelings – a materialistic desire to reclaim his family's lost building and become its owner, alongside a sincere wish to fulfill a long-held family aspiration.
Finally, he begins to climb the Tower of Babel – a dungeon fraught with various dangers and monsters, where one can obtain the power of constellations and ultimately, the power of God!
