Although LoC is a returner and GED is isekai'ed into a story as a minor character, both MLs have similar personalities, ie they are horrible little rat men you want to root for. GED has some of the greatest memeable faces as the normal/real leads give him reality checks and LoC has a similar face style at times in my opinion.
