And in answer to sis elsiec's question about favorite hugs and kisses (I have more than one):
This is a true "happy" back-hug as Eun-Tan are officially accepted by each other's family.
I always want to cry when I see this back hug. Here's Tan saying he won't see her ever again but he just can't help himself. I feel the pain in his words when he says, " I can't let you go. What do I do?" The dialogue is short but all the emotions are conveyed.
Of course, this back hug. When it broadcasted, I must have watched it a million times because of what Tan promised Eun Sang about letting her pass through any door in this world.
I guess I am a back-hug lover. There were many times in this series when I thought their hugs were more passionate than the kisses.
