Having followed Yoon Eun Hye's career since watching The Man of the Vineyard, I have to say that she well deserves the manic popularity with her Chinese fans. Apart from her sweet good looks, her portrayal of Go Eun Chan in The First Shop of Coffee Prince showed that her acting skills have improved significantly since her debut in Princess Hours.
Can't really comment much on Rain since I have only seen him on Full House, which I am still watching. All I can say is that he possess a boyish charm which is a sure formula in winning the hearts of adoring female fans. That said, I do find him rather endearing as Lee Young Jae in Full House.
