Forecasting Love and Weather

I did not like this drama but like most, I stuck on because I was attracted to the premise of it to learn more about what happens in a weather department and I really like the usage of weather metaphors for the relationships between the characters. But the plot fails to deliver, big time. The only people I was interested in were Donghan and family, Seokho and Taekyung, and Myungjoo and husband. Siwoo and Hakyung's story failed to keep me interested on why they should or should not be together. I didn't care. And for Kijun and Sujin, while I do appreciate that they did well in their development as people and a couple, but how could Hakyung and Kijun become so buddy so easily after what has happened? He actually cheated on her and she really actually caught them in their bed in their very own house! I do believe in forgiveness yes, but it really cheapens it so much. And in the end, what happened to the father and the police?
