Honestly this seems like something that works fine as a novel. Not saying the manga isn't bad but it doesn't add much. More content is always good though. I hope this series goes continues for a while.
While the story plot seems generic up to this point (chapter 4), the potential for interesting stuff to happen is present, thanks to the revelation at the ends of chapter 2 and 3. Can't wait for more!
A protagonist who worked hard and doesn't skip corners is my JAM, that's the stuff!! Thank you for the translation, The art is simple but doesn't lose detail on it, perfect for comedic and serious moments, I'm looking forward to the future chapter!
