I enjoyed the 2 seasons except for the ending, which to me, made no sense whatsoever. I guess it was to give the viewer a chuckle and to think about all that had to happen in order for the big mix up in couples, but then when I see there will be a season 3, I am not really that interested in seeing how it all came to be. Curious also that they did not provide an ending for the professor and his girl, and the wife he left, a lot of time was spent on them, but no similar ending.
As for the characters, my favorite was Sa Pi Young. It is beyond me how someone could cheat on her. Not even thinking about how beautiful she is, but that she was the perfect wife and mother, and they had the perfect family. Why would a guy need to go somewhere else?
Overall, a pretty good watch, just a silly ending.
