So those scenes that we got in previous chapters where a character dies and they see all their loved ones around them is what the 'paradise' Bon mentions is like. However, all of the characters that we see go through this eventually realize where they are, and the illusion breaks down around them. The paradise you pass onto isn't 'real'. You don't actually share it with your loved ones, as far as I can tell.
Everyone wakes up from the illusion, except the nameless boy. We will likely never know what his name even was, as he has already passed into paradise a long time ago.
