Osamu Dazai's No Longer Human

I tried to read the book titled No Longer Human a long time ago, because I heard that it is an acclaimed book. It was so difficult read that I did not get why it is acclaimed. No Longer Human is much easier to read in the manga edition. It is good that this kind of manga in English is published and gains a worldwide audience’s attention.BTW, this book is about a man who reprises the same type of mistakes, because he consciously and sometimes subconsciously understands that he is not qualified to live as human. So sad and pathetic.
