Not a good start for a manga, at least for my taste.
The mc is clearly pathetic and weak, in a world where power means everything. Yet we haven't seen any signs of this guy trying to improve his strength and skills, which he clearly lacks all of them.. Also clearly this guy is just ignorant and stupid, thinking that asshole of a grandfather would let his weak ass marry that girl.
Also him insulting the king & prince while the ignorant assholes can hear him like that (no matter if he's right or not)...
I dunno what this idiot protagonist is thinking, him saying stuff like that as if it would help the situation or make any difference.
I'm gonna give this a chance and keep reading, BUT, I'm not surprised if people drop this after reading this chapter and disliking the mc..
