Galaxy Book is usually very intelligent and knowledgeable about almost every subject, especially space and writing, but the problem is she is extremely shy. She is shy, bashful, timid, gloomy and anxious, always thinking the worst in social situations, hence why she usually avoids them. Despite this, Galaxy Book stays true to herself and secretly wishes deep down she would be someone or some people who will understand who she truly is, and then she will be truly happy at last, a happy ending.
