Both the lead character are nutcase, also experts in their field (Accounting for Chief Kim and Law for Mr Jo) trying to take down a big firm rotten by corruption and malpractice.

Both dramas are about a girl wanting to debut in the music industry and there is also romance going on in both dramas.

Male leads in both dramas (Hajime and Kaoru) have a lot of similarities not just in looks. Kahoko has an overprotective mother, Kazumi (Virgin Road) had an overprotective father but both girls are completely different.

Both has the same screenwriter
Both has the actors Hwang Young Hee, Shin Jae Ha and Kim So Hyun (Guest Role).
The Kim So Hyun character really is looks alike in both dramas, She is a pianist and She has some kind of relationship with Shin Jae Ha character, it's references from Page Turner.
The relationship mom-son (Cha Shik's Mom- Cha Shik) in Page Turner is alike the relationship mom-daughter (Nam Hong Ju's mom - Nam Hong Ju). The son/daughter is a little crazy and the mom is lovely and supportive the son's problems.

Both are medical dramas and both of their leads are so talented and ambitious surgeons but they are also cold-hearted.

both of them talking about achieving the dreams , baseball and Koshien !!
if you liked the baseball theme Rookies would be the drama that will show how hard and competitive the way to koshien is !!

Both titles blend modern day Korea with traditional Korean culture. They also both have the rich man/poor woman trope.

in TWY the future can be changed here the past can be changed thus uncertain ending for the main leads.

Schemes of a beauty is kind of a sequel to Beauties of The Emperor. You can see what Lu Zi (Joe Chen's character in Beauties) became in Schemes of a Beauty. Moreover, Luo Jin is playing the father (Emperor Gaozu) in Beauties and in Schemes, he plays the son, Liu Ying

Black *sounds* like a story similar to the Grim Reaper's romance in Goblin. Both are Fantasy Romance. Immortal falling for human love stories. One forgets the other...

**Edit - Black is totally different to Goblin, but the Fantasy, Romance genre remains. Both are also about supernatural entities on Earth and interacting with humans.

X-Man is almost like a prequel to Running man. The shows share the same always funny main MC Yu Jae-suk aka. the grasshopper. The shows also have similar content which involves missions. While the contestants in Running man complete missions to win the race the contestants in X-Man compete to reveal the true X-Man in hiding. Both shows involve celebrity contestant with one to be particularly exposed - Kim Jong-kook. If you watch Running man than I am sure you know Jong-kook's ever?asting love for Yoon Eun-hye and the teasing of other contestants. Well, the ''love story'' of this two to begin in the X-Man and is especially connected to one of the missions called of course. Both shows are full of comedy and are just a joy to watch.

They both portray strong female leads (in both senses of the word)

Just watch both of them. They're very similar to each other. They're both great and I'm certain you'll enjoy them both!

In both the main lead is a single mother whose husband died. There are two men in love with her, one is very rich and rather childish.
