Interestingly enough the main character dude was an isolationist otaku who didn't care for friends, only his games, so how exactly would he be well equipped to understand people's hearts in the isekai either? He can act like a splendid, utterly unselfish saint because that's specifically a fictional character type, not realistic, so an otaku would be exactly the right man for the job. But that's not real bidirectional interaction with people, by far. Thus this neo-Elrise is quite hopeless at it.
