Manga Romance

Could manga be the next big thing in romance?

With the global manga market being worth $5 billion and romance being the best-selling genre (in the US and Canada) it's surely a marriage made in heaven, particularly with young adults.
Romance giant Harlequin certainly thinks so. Harlequin Ginger Blossom is their new line of manga adaptations of best-selling titles: Harlequin Violet is a bit raunchy and Harlequin Pink is "purely romantic" (titles include My Real Fake Boyfriend and Three Wishes).
The sequel to Meg Cabot's young adult book, Avalon High will be split into three separate mangas under the umbrella title Avalon High: Coronation.
So what do you think? Are you interested in romance mangas or are they just for kids?
