Older kdramas often normalize and romanticize things like this, including wrist-grabbing, although 2016 isn't that old either. But turns out similar thing happened in S2, so it's the writer's mentality I guess.
Making the ML being respectful for the rest of the show (actually not really, he asks her to sleep with her) I don't think it's better, only further proves the problematic side because that's when they normalize the kiss, making it just another pre-relationship bickering between the couple since the ML is a good man. Of course a ML will be described with positive characterize. Different with the senior doctor who kicks the FML, he's a jerk, a villain, beside his act is indeed an assault, people will have no problem to found the act as a bad thing.
