Okay I like the story and MC but this is annoying and starting to get frustrating.
1) why are the chapters so short after one? For a story like this 20 pages is minimum and 30 to 40 allows for good pacing. As a courtesy the first chapter should be 50+ pages to get all the exposition out of the way and establish the setting (so everything is setup for the actual story). We shouldn't be on chapter 3 and still standing in one place and just NOW explaining that it's been a thousand years
2) The random overprotective perverted Yuri knight is as annoying as usual. You can be defensive but your precious princess would have actually DIED had he not helped, show at least a little graditude. Also as you can clearly see the person you keep insulting and treating could kill both of you in five seconds. It would make sense if they were close enough to know each other's personalities, but they don't know anything about this man that could destroy them and the whole forest on a whim and she can't even hope to damage him. The last thing any sane person would want to do is agitate or any way anger or upset him. Also if you're a devoted knight at least listen to your master, and you CLEARLY can't protect her yourself (not even from the obvious threat of bandits). Just accept his help and be grateful for it.
3) What is with this random conflict? The dude just said he's from a thousand years ago and have been mentioning CONSTANTLY since he showed up that he was lost. The only thing he's been doing is asking for directions and he JUST said he's never seen the outside world before. Why would you blindly follow him? I agree with the MC he has been completely upfront with the fact that he has no idea where anything is. In contrast neither the princess nor the knight at any moment expressed that they were lost. In fact they provided the MC with information he didn't have about the area. Anyone would assume they know where they are and would say if he was going the wrong way. Also someone doesn't go at the front because they necessarily know where there going. The MC was at the front because he could let effeciently deal with the underbrush and was their literal body guard (so he deals with danger first). The idiot knight has no right to get mad at him or act like that with the whole "you should have done that from the start". The princess (who has some brains in the pair) at least should have realized everyone was lost and said they should make a plan or something, but nope. She's dumb too apparently. The second half of this chapter was just a waste a time.
So far this is just bad and frustratingly so. Which is ridiculously annoying, because I'm interested in the premise and want to like this story, but there's nothing even slightly praise worthy here.
