Won Jin-A plays Go Mi-ran a student who is working on an entertainment programme as an assistant and is in a shallow relationship with a fellow student. Ji Chang-wook plays Ma Dong-chan who is a tv producer at the same station and is in a serious relationship with a newsreader. Circumstances means that the two leads are to be frozen for twenty four hours in a tv programme exclusive, sadly it all goes awry and they end up not being frozen for a day but for 20 years. It is a clever idea and as a romantic comedy it is enjoyable because the actors do a convincing job of making the feelings between them believable. Some interesting side characters and stories which I think should have been explored to make it more interesting. Overall a good story but too many things going on and little background or depth given to any of the stories apart from the romance.
