Quickly Wear It, I Really Don't Hold Grudges

It's very interesting, with a different perspective. In other novels, the time traveler takes revenge on the original owner's behalf, but in this book, the demon lord acts as an assistant to give the original owner a chance to improve himself and take revenge himself. He also encouraged the original owner to do more good deeds and accumulate merit in exchange for merit points. He has a very upright outlook on life and a good writing style.
