One good thing about a stupid, annoying MC is that even when he's getting beaten up, it's nice to read. Unfortunately that's the only good thing about it.
I love how the previous hero was thinking that he was being compassionate by not killing the literal Evil Dragon, but it is just instead pushing the problem down the road to people less prepared. Ah consequences, you've got to love them.
At first I was thinking why did he save nea, then I read it again and now I understand why, if nea dies, dragon has full control of it's body which is bad
