I will be honest there is so many questions that they didn't answer like why make up all that going to jail thing if he will end up working on the fertility clinic... also the cheating thing of Dong-a and all was not that necessary since there was already a lot going on... also they didn't need to do that to her at the end they could have made the ending better at least.... there is so much going on it was overwhelming.... don't get me wrong I do love the idea and the plot is refreshing andnice
