I'm a rezero hater so all i can say is that, this manhwa is 100 times much better so I don't think there's a consequence like that. i bet he's cursed
I don't think there is since he's not even supposed to be excited about reliving the same day and dying over and over (painfully most of the time)
the consequence is supposed to be going crazy and giving up but our mc is an insane bastard, as insane as the rest of his squad, so he actually likes to suffer and push himself over the limit
What if there is a secret consequence for all the times he died... something that would make him regret feeling excited about repeating days (Rezero ptsd)
