Alright, great beginning structure wise. A lighthearted isekai adventure is something many will flock towards as it’s just interesting and leaves a lot of ideas to be explored or used. 

Our protagonists morals are always a nice to thing to have in these stories too, as they can form nice layers of defence for allowing readers to assess his actions.

Now that being said, this is a nice start but could use some refining (keep in mind its only my opinion though.) I think you are switching between first person perspective to third person omnipresent. Which confuses the readers a bit, maybe use italics for one tense and normal writing for the other. It just needs to be clearer. 

Another thing, Description needs work. Not enough showing or painting a scene and too much telling the audience. E.g Yes, telling us the lady is pretty is cool, but some more given to describe her and let the reader come to that conclusion would make it a stronger point. 

Just needs more practice I think. But that’s my own interpretation there.
