In this case, my utter HATRED of the "kindergarten kismet" trope. When I saw that this Drama was built on exactly that trope, I assumed I would hate the Drama. But, it triumphed, and I loved it.

What I loved was that it played with the trope, mocking it, analysing it, and teasing the viewer until the final episode as to whether the trope would come true. The side couple were well done, the bar owner's arc especially lending some real emotional warmth and depth to the light frothy sweetness of the main storyline.

Another big plus was the short length. Four hours total runtime was just right, no angst or pathos padding out a longer series.
