Infinite Level Labyrinth

[Currently in the process of rewrites (cuz it's so bad even I don't wanna admit it's my novel).] It was said that the stronger the player is, the higher the labyrinth is for them. But what if you are just too strong and can never meet the ending of the labyrinth? Jungmin Kim who had been playing the ‘game’ for as long as you can imagine had one day realized he still has a very long way to go to the ending of the labyrinth. As he progress through the labyrinth surpassing even the highest floor reached, he made new friends and companions, not to mention enemies. But he also lost them every time. He knew that everyone he met will ended up meeting their end while he wouldn’t and so he had stopped making friends. Until that very day of his meeting with the 'ending'… Witness Jungmin in his adventure through the labyrinth as he smiled, cheered and suffered for his connections from the very start to the end!
