So he like… just chilled in a cave for 10 years lmao?

I think the manhwa could have explained it better but from what I understood, he wasn't physically able to leave the cave until his master deemed him "ready", like he wasn't physically able to climb to the top of the cave until he had mastered a minimum of techniques
But I completely agree that at first glance, it totally seemed like he could have gotten out at any point lmao

Nah I know he was stuck it just felt like a lowkey silly way to keep him outta the picture for a decade haha

I agree, it could have been done better
