All those romantic things you can find in korean drama (However, they're starting to open up, similar to thai, check out Snow Queen, Que Sera Sera, and Something happened in Bali). That's why I think it's better for each culture or country to stick what they are best at, so we can have variety to choose from. Thai lakorns that have r-scene, slap/kiss, na'rai I admit they are unrealistic but it offers a fantasy. Ahaha.
Just compare it to food, if you have one dish everyday you will eventually get tire of eating it, it's better if different dishes were put out on the table for you to choose from...since each person has their own taste.
