The series Tunnel was inspired by the unsolved Hwaseong serial murders just like the movie Memories of Murder.

The atmosphere these two dramas give off is too alike. Mystery. It keeps you guessing. Addictive, wanna watch next episode ASAP, and painfully bearable at times. They both have the same actor Kento Kaku. If there's a Japanese word for Makjang (Korean), let me know what it is called. I don't think this genre of dramas is an equivalence to the Makjang genre in Korean dramas. This is in some ways alike Makjang but is added another ingredient on top. This is a type of J-dramas that I haven't known its term yet. It is more realistic than makjang and is added a Japanese society into it. It has a Japanese flavour, duh!
I find Makjang cheap, but the J-drama ones are made better.

In Behind Your Smile Zhao Yiting only sees his revenge, but ends up falling for Lei Xinyu in the process. However, Another Miss Oh Park Do-kyung gets his revenge on his runaway bride, but finds out he is mistaken and has spoiled another woman's wedding. He gets entangled in her life and ends up falling for her.

The premise sounds pretty similar. The rich guy moving to a poor neighborhood to start from the bottom and the poor girl that helps him out.

Scarlet Heart is set during the reign of Kangxi ( 1661 – 1722) while Rule the World is set at beginning of Qing Dynasty. The male lead is Huang Taiji (the first actual Emperor of Qing Dynasty ) while his father is Nurhaci, is the founder of Qing Dynasty.

Scarlet Heart and Rule the World have a similar plot: a woman who goes back in times and gets entangled with the princes of the reigning dynasty.
So if you like the first drama, you could like also the second.

Both are absolutely amazing! Really similar. In signal, they communicate through walkie talkie, but here they communicate through dream. If you love Signal, you absolutely will love this movie.

The drama-version of The Myth has a lot in common with Ultra Reinforcement. Both star Chinese Paladin actors (Hu Ge and Wallace Huo, respectively). The premise is similar. A modern guy stumbles into the past and changes things around him by bringing knowledge of the future, similar to Connecticut Yankee in King Arthur's Court by Mark Twain. But while Ultra Reinforcement stays a parody, The Myth builds an epic-long story and keeps the lead in the past for a lot longer. Unlike Ultra Reinforcement, the character in the Myth ends up being changed by the time period. Also, there's that whole switching back and forth between the lead and the people in the future trying to figure out where he went. If you're intrigued, try it out.

It actually is very similar to another enjoyable parody Royal Treasure with Luo Show, Huang Bo, Sun Hong Lei, Zhang Xi Ying, Huang Lei, Wang Xun, and Zhao Zanilla. I've never seen Running Man, but I imagine it's a lot like it but in a historical setting. The element of parody is intense. You have to treat it like a comedy, and then be surprised by the more touching moments. Royal Treasure's end is more heartfelt though.

they both deal with affairs in a more realistic way. the men in both kinda "love" the other more, right up until the end. they both have great cinematography and open endings.

It's not so much the story (they are both first love stories though and high school life, coming of age etc though) but the feel. Just very feel good cute movies with a bit of serious touch. Also touching on the trials and tribulations of growing up.

The show will be based on the Korean version. I hope it will meet the expectations
Choi Shi Won will be playing the male lead

The protagonists are great analyzers who work for the police and use their skills to deduct and solve cases.

an unconventional male lead who is also a wealthy son but has many on going personal/mental social issues. Ends up falling for the girl that is hired to work for him. Characters are better written and portrayed here than in RL. IMO hehe :)

I am now in the second season and it is just as intriguing. I came to this site to find out if the actors were in any other similar drama. They are excellent especially the two male leads. The only thing I can compare this drama to is the Korean drama The Voice starring Jang Hyuk. There is a film starring Wallace Huo called Inside or Out, with Simon Yam and coincidentally Jang Hyuk. Don't miss either of them or both seasons of Evil Minds

The male leads are both very soft-hearted.

The female leads are both very hard working.

The plot might not be very similar but at some points it has the same vibes
