Both dramas have misteries around plane crash and are alike. Action and suspense theme in both with a little romance too.

Both dramas are really cozy, interesting ans mysterious. I think the relationship between the two leads is really similar. The two leads are investigating together in both dramas, and they are able to catch the bad guys with the ability of the female lead in both.

In both series a underdog like main character has encounters with psychopaths/murders and their influence changes his nice and quiet personality to something more scarier

A boy is part of a rich family until they abandon him and destroy his life. Later on he comes back to take revenge. He approaches the female members of the family first.

It's similar a bit naive female lead and smart male lead .......... First about Something About 1 % , male lead and the female lead first meet their about start conversations they are not liking each other , the drama like hate then love relationship , contact relationship , bossy type male lead . In other one the well intended love ........ Female lead got worng information about the the she couldn't live long and the person who she looking for to help her it the main male lead..cool good looking, businessman . She ask male lead to help her ,but the male lead put forth the exchange of help with the condition of contract marriage,but drama so cute comedy , after the watching drama suspense open that male lead fall in love with the female lead at first site .

both Love with Flaws and Yamato Nadeshiko Shichi Henge have that basic "female lead hates beautiful people" kind of a story ;)

Story of Yanxi Palace is a Chinese and darker version of Dong Yi.

Both dramas follow the same scenario: slave rises in power with her intelligence and wits and earn the love of the Emperor in the process.

Both have scheming consorts, splendid costumes, amazing heroines, sismance and a love triangle.

And both are absolute must watch.

both kinda talk about the same subject. the FL from HSH lies to her fiance and mother in law about her families house and pretends to live in an upscale apartment that's really owned by her friend.

Both films are about lesbian couples and deal with the pressures and prejudices they face in South Korean society.

Both series give same kind of feels overall. Both have a bit of a fantasy twist, they have the rich CEO - poor girl setting and hate to love relationship.
