Han Daesung, Back From Hell

Middle school student Daesung Han's life takes a dramatic turn when he finds himself mysteriously transported to a nightmarish realm that operates under game-like rules. In this hostile environment where survival is far from guaranteed, he must navigate treacherous challenges and face formidable adversaries. After what feels like a lifetime spent fighting to stay alive in this hellish dimension, Daesung is presented with an unexpected opportunity to return to his normal life on Earth. Upon awakening, he discovers that while his experiences in the other realm felt like decades, only a fraction of that time has passed in the real world. However, Earth is no longer the same place he left behind - strange dimensional rifts have begun appearing, bringing with them dangerous creatures and forcing humanity to adapt to a new reality where specially trained individuals known as Hunters protect the population. Now back in his teenage body, Daesung must readjust to a world that has moved on without him while carrying the weight of his experiences. As he struggles to find his place in this changed society, he discovers that his ordeal may not be as over as he initially believed, and that the connection between the two worlds might be more complex than anyone realizes.
