Both of them are about two older adults that argue and have great chemistry together. Both of them are just genuinely good and are a pleasure to watch.

Both are: nice and poor girl has to marry an arrogant, mean and rich guy who is already in love with another girl.

When you enjoyed one of this drama, you will enjoy the other one, too. Main leads characters are the same:
The guy is a weirdo, getting annoyed fast by the female lead, and is arrogant and sometimes mean. The girl is cute, very nice but also pretty naiv. Fated to Love You is about pregnancy/marriage while Youre Beautiful is about band life/music. But relationship of the main leads is pretty similiar.

Main lead has a second chance. Both leads become younger. Both learn a lesson...

TROT LOVERS and PROTECT THE BOSS are both Romantic Comedies. Both have the couple start out disliking each other. Then they get close after working together. Both have men that mature throughout the drama. I would described both as fast paced and fun, because they both are upbeat and there is always someone running here or fighting there..

The couple also pretend to be in love and enter into a contract marriage.

Light-hearted and fun to watch. It is just like Umi no Ue no Shinryoujo where Dr Kouta for his female patients, Dr Shiba, the vet falls for the female owners!

Both the same type of chinese historical sci-fiction wuxia drama involving swords.

That same quirkiness is found in both. High school drama dealing with bullies.

Marriage Blue also focuses on the trials of multiple couples relationships.

They have completely different plots but in both cases music is a very important part of their lives. Both movies manage to include a lot of music in the movie without it seeming weird or out of place.

Both THE MASTER'S SUN, and SPELLBOUND are cute Romantic Comedies with spooky ghost activity.. Both have a leading lady that sees Dead People and a leading man that helps her to lead a more normal life.

Both protagonists are out to save a little girl, both stories are full of blood and violence, and both stories have an amazingly hot guy.

Both are historical dramas about a strong forbiden love. Both have very strong characters, a lot of action and political intrigue.

It's also a gangster movie but, it's a little more intense. Good none the less.
