a protagonist that will go fangirl over side characters on every page... SOoOoO COOL!(sarcasm) those that were complaining about strong protagonists on isekais finally got the MC you wanted?
"can I really be like them?" - no, you can't. You are a weakling that is just their mobile smartphone that can only use google maps. Actually, the MC doesn't even need to reach the end of the dungeon, he just needs to map it.
