@phoenixtear not all people brain goes "yaay, I got summoned to isekai! Time to do the mainstream, adventuring~"
This time, it's more like "admiration at the first sight" and "I wanna be cool like him".
If people were asked "what will you do when you got to isekai and got the title of something like 'hero'?" there will be many different answer to that like "I want to live a slow life" "I want to make a harem and impregnate many women" "I purely want to explore the world"... not all people want the same "explore this fantasy world with a nice status"
