My Pointless Struggle In This Cruel Fantasy World!

Edelgard, A story about a kingdom that stood guard as the greatest empire of mankind. Standing as the bastion that protected humans from the demons that lurk among those that wake in the daylight It was a really niche book that didn't garner much popularity on the vast libraries of webnovels on the internet, it was an intriguing book that only I found enjoyable but I never thought in my wildest imaginations I would end up in it. Usually Transmigration stories go along the lines of the main character fusing with one of the character of the world you are sent too, but something unexpected happened in my case. "What a bummer...." "If you have time to laze around, get to work you jerk!" Oh! did I mention, whoever transmigrated me did a terrible job at it and now I'm stuck sharing a body with one of the worse characters from the book!! POV change : There are lots of mysteries in this world. from the myth of the Ancient 7 dragons that shaped our continent to the tale of how a single slime took down the 3rd Emperor of the Elves. I never thought I'd experience one such mystery Until- "Ayo, What are you writing there!?" "Nothing, go back to minding your own business" Until I started sharing my body with someone otherworldly. "You should really start packing or we'll be late for school" "Oh shut it!" And how I ended up sharing a body with this man is a mystery and one that I never forsaw would change my life drastically, for the better or worse I didn't know at the time. To tether the knot that lost it's hold. A/N : English isn't my first language and I might make lots of grammatical mistakes and this is my first book. I hope you guys can kindly point the mistakes out.
