I've never been more annoyed of a Kdrama couple. They are all over each other with no reason to like each other when they hook up. At some point the male lead says something along the lines of "I liked you from the first moment we met". So would that be when she shoved you off a treadmill or when you caught her violating your toilet?
I find the obsession with women being judged by their smile and weight to be very offensive and outdated. Almost as ridiculous as having mental disorder-like symptoms from one traumatic experience as a child of seeing people fake-smiling. And honestly, how many times does she need to fall over? She would have died a long time ago if she walks around everywhere falling, waiting for someone to catch her. The show has a few enjoyable moments such as the grandma and wingman, but overall is very generic with a weak story.
