Well, one common element is the idea of a special encounter. Maybe it's two strangers who meet on Valentine's Day and their lives are changed forever. This could be in a bustling city or a small, idyllic village. Gifts are also common, like a bouquet of red roses given by a suitor. And there's usually a happy ending, whether it's a new relationship starting or an existing relationship being strengthened. For instance, a couple that has been having some problems reconciles on Valentine's Day in the story. Also, the color red often plays a role, representing passion and love, whether it's a red - heart - shaped balloon or a red - ribboned gift.
Love is a very common element. It could be the love between a couple, like in a story where two lovers meet on Valentine's Day and have a magical evening. Another common element is the use of Valentine's symbols such as hearts, roses, and chocolates. For example, a story might have a character receive a box of chocolates as a sign of love. Also, a sense of warmth and coziness often pervades Valentine's bedtime stories, as they are meant to be told in a relaxing, bedtime setting.
