As a book or story progresses, one of the things that can keep it engaging is the character development. Authors make characters seem more "believable" by giving them a history, personal characteristic, hobbies and other background elements. In a series, the same characters return and readers may understand from previous books why, for example, one character hates rooms that are painted green. Even when a reader doesn't understand the reason for a character's quirks, those things make the character seem more realistic. Do you know why your co-worker always wears that purple tie when giving an important presentation?
