It is very interesting when it comes to the idea of love and love at first sight. Since every episode is really short, you can finish all 3 seasons in a day wich is actually a good thing. A day before us depicts the path of love in an interesting and realistic way. It shows how everything happens. I would recomend this to romance lovers cuz it is short yet amazingly done. You really get into the characters and their feelings and you see them develop really nicely. Out of all the 3 seasons I personally think the first one is the best simply becauseit gets you into the story, first two and few of the last episodes are the best of it in my opinion.
