Are people forgetting that he's not really in for a happy future if he just tries to repeat his life (something that would take a long damn time and we have no idea of knowing if it would even work), but a problematic timing error on an attempt to get on a train?
They could really tone down the cringiness of him, but judging by most of what I read here you have to set the bar real fucking low to not have the native readers intimidated by a main character.
