Review Detail of Bikaa in The Way of a Demon Lord

This novel is actually good if the author should use the character's name during the conversation, not use him and her. For example (I took this from chapter 22 atau 23): "I just hope you have yet to lose your skills." He muttered while he stood up. "What?" She could not hear clearly. "Nothing." He left. Just to read this conversation, I have to use my brain to determine who is speaking and who is answering. Actually it wouldn't matter if it was just one or two conversations like this, but these were all conversations in the novel using him and her, which gave him a headache.
