Classical Grammar in Just 6 Hours by Yazawa Thank you for viewing! You can see very easy-to-understand explanations with video materials. There are a few places marked with a highlighter, as shown in the photos. It was kept in a book cover, so it's very clean. I also feel like the main body is slightly bent, so please check the photos. Of course, the explanations and mini-book are also included. Please consider purchasing this, taking the above into account.
