I really like the story of the main characters and how they love each other. Even at first sight, I thought that the outlooks of the actor and actress somehow matched so well and created a good chemistry already. I would still feel that the energy and characteristics of the female lead are too idealistic, but I guess it makes sense for someone who survived that kind of tragedy with positivity. I normally don't watch similar theme dramas because I can't handle these kinds of hardships and losses, but this couple really gives me a soothing feeling. Their story is really well-plotted.
The second doctor-firefighter couple is also cute with meaningful stories of their own, though I think that they should have more time telling the stories in more detail.
Of course, there are things that I don't like in the drama, such as the evil reporter. She committed a fatal unethical deed especially in the journalism industry since the beginning, got reported and all; and yet, somehow still stayed in the same position to do more evil things.
But anyway, I can oversee those and enjoy the other parts of the drama. The OSTs are also nice, I like the song "Day Dream" the most, very sweet.
