I'm a scholar, but this is the first time I've studied like a wild type. If I hadn't seen the introduction page, I would have still been struggling with the book or not progressed in the basics. @.@... As you said in the middle of the lecture, I don't know about the owner of the relationship, but I listened comfortably ~, listened to the basics, and am studying again, and it's all in my head! I love how you explained it in an easy-to-understand way! It's a shame that there are only 5 stars><...
