I can't say yet about the skinship, but if you want great romance give Beautiful Life a shot. This may be the most organic and affecting portrayals I've ever seen in drama land.
Currently airing chinese drama: My amazing boyfriend (main girl is korean model, this drama seriously had alot of kissing and it was really cute, highly recommend)
I've watched all of these (except for chinese one). I'd rate them like this. It's okay That's love > Queen In Hyun's Man > Healer > Marriage Not Dating > I Need Romance 3
They Kiss Again has a ton of kisses, but its a sequel to It Started With a Kiss, which has like only four kisses? In they kiss again, they're married, and have like thirty or more kisses?
