Hyoyeon attended the celebration for the official launching of her book on July 1 at Seoul Seongdong District's Espresso Room. At the launching, the singer revealed her feelings about the publication, stating, "The book has finally been published after one year. I was able to truthfully and honestly include the stories I have been thinking about for a while." 

The newly blond babe also gave her own definition of style, professing that it is always "ing" (in progress). She added, "My style keeps changing with the flow. As I gain more experience, my styling could change. My current looks isn't the end but it will keep on evolving. I think I'll be able to show a much more dramatic color," displaying confidence.

The self-professed fashionista also stressed the importance of accessories, asserting, "Whether you wear a one piece or something more casual, accessories is key. Even when I wear swimsuits, I accessorize." She added, "If you properly match your accessories, you can appear very feminine, sexy, or emphasize your cute side. It's good to use accessories in a variety of ways no matter if they're small or bold. These days, I think even a hair band can look pretty," generously sharing her know-how in fashion. 

'Hyo Style' explores Hyoyeon's stories of beauty, fashion, and life in the hopes that they will help those that want to become beautiful.
