Recommandations

Quite same plot, but the action is different. Maybe because I'll Die Soon is about a middle-aged man that want to live every day like is the last one, while My Friend Is Still Alive is about a high school kid that wants to die without regrets.

I watched these dramas one right after the other and I felt like I just watched the same drama twice. I personally enjoyed the romance better in Mask, but both dramas were good.

diff genre.....yes...but...

they both have very ambitious young men determined to make their dreams come true regardless of the obstacles standing in their way

lead actors..wow...

A somewhat younger guy and older women pretty much the same plot.

both dramas are set around news reporting and reporters and the leads have similar personalities in both dramas, though Jealousy Incarnate has more focus on the love triangle than Pinocchio

When I first saw the transferring to another hospital with a poor condition in D-Day I immediately remembered RDTK. Although it won't be the focus in D-Day, I can still see the resemblance especially how the lights get turned off in the hospital. The dramatic accidents are very similar to those in RDTK because they have a similar feel. D-Day is based on Disaster genre, so there is more of that there. And they both have light romance that develop slowly.

Different stories but you just can`t not watch any of them, in both romance, vampires, and hot guys are there :P

Slightly different but but still romance, vampires, cuteness in both and if you liked one you will love the other too.

1. Lee Won Geun is the main lead.
2. Both have sweet, youthful content.
3. Both have love-triangle

1. Lee Jun Ki is the male lead of these two dramas so if you're a fan of him, you should check this out.
2. both are historical dramas and the characters of Jun Ki both have complicated background. In Iljimae, his dad is called the traitor of the country while in moon lovers, his mom hated him a lot. And family is the main key thing to his decision. Revenge.

This is literally the original series that "Pretty Li Hui Zhen" is based on and follows the plot and characterization in it quite closely.

If you are finding some Kdramas with that second male lead syndrome then both of these dramas are made for you. Those two 2nd lead are caring, always there when she needs, a sweet-hearted guy but female leads didn't choose them in the end... =(

1. Both of these dramas have the sweet, light-hearted content and based on lives of college/ high school students. In "To the beautiful you", Kang Tae Joon (Minho Shinee) is a high jump competitor while Kim Bokjoo (Lee Sungkyung) in "Weightlifting Fairy" and her partner, Jonghyun (Nam Joohyuk) are majored in weightlifting and swimming in respectively.
2. The main male leads are both known as the "hot boy" at schools with handsome look and amazing talent in their own majors. Somehow, they also struggle with their sporting career. If Kang Tae Joon got an accident that could potentially ruin his future career as an athlete, then Jonghyun's trauma is the only thing that gets in the way of his success.
3. Kang Tae Joon and Jonghyun each used to be really cold-hearted until the female leads come to light up their worlds.
4. There's always a second female lead who had a relationship with the main male lead- "To the beautiful you", Seol Hana (Jiwon) is his childhood friend and loves him for a really long time while Siho (Soojin) is his ex-girlfriend who still has some feelings for him. Both always try to annoy the female leads.

Main character is also a darling daughter, and her love interest also started from nothing. The revenge plot comes from a different direction, and it's much cuter/way less melo.

The Investigation in Cold Case is more direct on crime stories. The Specialist drama, it also involved with crime stories, but both have different approaches on investigating. It is not like pure Sherlock and Detective investigation technique. It is more evolve in thinking patterns in a creative and logical path.
