Secret Garden is about a stuck up rich guy meeting a poor girl who is not very girly and inexplicably falling for her. Coffee Prince brings the same feeling of funny and romance with an easier going hot hot hot male lead and an easier going girl who looks like a guy. In Secret Garden they switch bodies but in Coffee prince there is a gender mix but it is ENCHANTING!!!

just because Hongo Kanata and Takanashi Rin were casted together in both shows.

As major themes: both are funny, heartwarming stories and feature the main characters growing up and becoming more confident adults.

Other similarities include: featuring high school reunions although at different scales; There is definitely an element of who is the daddy/husband mystery in both although for very different reasons; Both have really cute/inventive title cards for each episode and are 16 episodes, so on the shorter side for dramas

Totally not the same, but both are melodramas with bullies, murder, and mysterious pasts in their plots. Both have Kim So Hyun in them, and she's always fun to watch. Truly talented young lady. Missing you is a lot darker and bolder but both are super interesting and hard to put down.

In both the male lead has the kind and gentle character, that women wish their husband would have.

Same kind of feel in both dramas. The female starts of small and weak and gets stronger towards the end. Both are designers.

Both stories are set in the same dynasty as well as the same element of a marriage, adding humorous features and scenes.

Jin Shi Jia is also starred in this drama. Both dramas follow a somewhat humorous storyline with dramatic elements.

The big brother sacrifices himself for the little twin brother. The drama has only 4 episodes and it's worth watching. Don't miss it!!!

Although these two movies are set in completely different times and different story lines, both movies are about two men who are from different sides of war becoming friends.

It is about a lowly singer becoming Empress of Han dynasty
it is a good drama for those who like historical dramas

well it is not like The Investiture of the Gods but at least it is a martial arts drama

Both are slightly absurd and centers around a rich family, although An Inspector Calls leans more on the silly side.

Both dramas involves a male lead who is considered a very good catch and sought after by women but was never interested in women. They are mostly focused on their career.
If you like cold uptight male leads who eventually transformed in a softie when they finally fell in love , then these 2 stories are for you.

If you think sending love messages that you cant speak of to someone you love and hoping that someday destiny will eventually deliver it to that love one is poignant and romantic...then you will find this 2 movies touching and heartwarming
