Climbing the Tower that Even the Regressor Couldn’t summary:
My girlfriend, who was drunk and lost her mind, suddenly said strange things.
"Su-hyeok, I've regressed."
"Regressed?"
"Yes, I've come back in time."
"Are you crazy?"
"You are the only hope for humanity."
And then I was taken to the tower… But it doesn't matter!
Regressor? Tower? Trials? Whatever it is, It doesn't matter but what I know is I'll conquer this goddamn tower!
