I can't read Korean, so I don't know what the real title is. This book is part of a series with other more difficult Life & Death books in it, so my guessed title may not be a unique distinguishing name. There is no ISBN that I can find. The book is published by OroMedia with a No. 52 on the spine, so I guessed that would suitably distinguish it from others in the series.
If someone else is able to work out the real title, they could easily change it on the page.
