Another historical drama about the corruption of power. Also, they are both about the strength of the people, good over bad, and the struggle for justice.
I find that even though the plot lines may be different, one being about a princess and one about a vampire, they have very similar characters and character relationships.

The female lead in both dresses up as a male, for their survival, in the early part of the drama. They are both bright and friendly, though, Jo Yang Sun isn't as thoughtful and clever as Jeong Myeong. Both have a strong fate with the inner workings of the palace.
Both male leads are kind and caring, and will go to the lengths to protect their leading ladies. Their caring love is what makes you heart race while watching the drama. Difference though, Kim Sung Yeol is a vampire and Hong Joo Won is a bashful scholar (well he moves up in rank through out the drama) .

The royals in the drama are similar too, where, as much as they want to fight the corruption, its extremely difficult. In the process, they lose their original goal and stray. Their mission throughout is continuously remind themselves of purpose and try to find the right retainers.

Is the same main actress, but on a role totally diferent , the story is very good and the romance of the main couple is wonderfully perfect, I venture to say that is my favorite Kdrama, the couple makes me want to have a relationship, it's worth every minute.

both dramas both have issues with a huge inheritance being given to a female although it was the male's family own first.

Also a story about the legend of nine tails fox but with several stories.

The same idea of people who were given an extra time after their sudden death

I think that Kikujiro & Lost and Love have lot of similarities, the first one is that they are both kind of Road movies, we got to travel with them, visiting, Japan and its sceneries in Kikujiro and the same with Lost and Love but this time in China. Two protagonists (Kikujiro with Masao) and (Lei Ze Kuang with Zeng Shuai) are looking for someone and in that purpose they have to go on a long journey, they meet many people on the road, funny, kind but also some weird and crazy people as well.
Cinematography is breathtaking in both movies too.

Only the genres are a bit different cause Kikujiro is more funny and crazy while Lost and Love has a sad but very heartwarming tone. Two gems in my opinion;

it is another short drama about school, friendship execpt this one has the characters of a rookie band called "astro"...

both have teams, fighting for justice,,,,,some exceptional martial skills,,,and main lead of both shows have quite a intense past

Both is a story of love that is not just based on appearance but what important is in the inside that matters.

Both romantic comedies involves a rich guy with a poor but cute/nice girl. Similar themes. Great actresses in both, though the overall acting of the cast in fated to love you is probably better.

both have funny characters in addition to the main cuple, they have not the typical story of romance, maybe some love triangle but without becoming awkward to watch.

In both series the main woman isn't considered a suitable partner by the men around them. They end up meeting younger men who will help them change themselves.

In both series the woman wants to be a teacher and she enters in conflict with a student.
