at this point i really can relate to those garbage story isekai mc that wanna be incognito, this seems fuckin tiring mentally so far and it's just constant pressure from people important that they really wanna meet this low ranking individual without ever considering their own position and natural pressure.
I get that they wanna meet him cuz of their achievement but can you at least make it casual first (e.g. letter of invitation) so to not overpressure them to flee or go incognito cuz the jump of popularity from nobody to that guy is really high.
Wtf was that one sided "hero" title granting like he just get labeled as "hero" out of nowhere so to make him do the job of the "hero" and expect the citizens to always be protected by this so one sidedly called "hero", and the cherry on top to make him can't flee the king send a platoon to him to respect him and call him "hero" just cause. He just saved a ship from dragons (and maybe prevent some damage to the surrounding dragon's area), not like he saved the world from a primed nuclear bomb.
Me looking at this situation really seems like the king wanted to leash this guy to the country so he can do jobs at times needed from summons and such, which can be really overbearing if not handled properly. And given how lots of high ranking people been acting lately for now, it's not a zero or low possibility of it will be happening.
It's been happening quite a lot now in this manga and seems like some bad people will eventually leach to him, given how much people been saying "it's better you don't know" to some possibly life changing information just cause.
edit : i dont even know what is the value of this "hero" anymore, like most of them are world savior last time i know, but this time it's not that grand of things seems like. i get if they wanna give him "dragon slayer" cuz dragon but then why also "hero" when majority of people there don't even know him and there is no grand world saving task in his hand is just why.
