To me, the best kissing scene I have seen so far was Park Shi Woo and Moon Chae Won; The Princess Man (episode 21). Finally, participation and reaction, other than surprise, from the woman. I loved the way she leaned into him; it was tentative and sweet, not at all aggressive. I think asian dramas are a little cautious in that area, and I agree, too much emotion gets repetitive and stale. But, this scene had just the right amount of everything.
