The plot lines for these films are very similar; a normal high school girl gets prettier as the film progresses in order to grab the attention of the most popular guy in school.
Cute, sweet but cliche.

Both dramas have a common theme of keeping a marriage going just for appearances. Both funny and have great actors.

They both have similar plots: meeting with a past lover/ crush and years later the female leads looks have deteriorated and meets the lead guy again.
Get Karl was a comical drama just like she was pretty.
