In all seriousness, if I was him and got to a dungeon and someone told me a wave of fire of unknown origin just wiped out all the monsters in the dungeon I'd have no doubt what happened...guess we get an early chance to check out just how strong the dense MC syndrome is in this one
Kinda reminds me of Murabito desu ka where we have a person 'protecting' another person, but really just stifling their growth to an extent that they can't actually do anything themselves. Only it's worse here.
made me remember the typical generalized asian mom. too protective when the kids young, then expecting the child become independent when they are already get used to being spoonfed lol
