Author, I'm energetic right now, could I take a look at your book and comment on all the flaws I could see? Not much in grammars tho! Fufufu!
I'm just askin' because other author getting offended when telling honest Fufufu
Some grammatical errors are visible, maybe you could download the "Grammarly" App that I was talking to. It could help a lot. Of course, it's your choice
