I caught up to chapter 155 of the manwha, and am eager to continue, so I’m going to read the novel next, so I have two questions: 1. What chapter of the novel is chapter 155 of the manwha, and 2. Is the novel different enough from the manwha that I should start at chapter 1, or is it close enough that I can resume where the manwha is at?
