Both dramas are melodramas which both a childhood and adult part. Both dramas make you cry episode after episode because everything that happens to the main characters is so sad.
Also the shipbuilding theme in May Queen is comparable to the Fish Farming theme in Golden Rainbow.
Kim Yoo Jung plays the younger version of the female lead in both dramas.

These two short dramas are very similar and I just love them both. Both depict young couples who fall in love but face trials in their relationship. If you love one, you would definitely love the other.
I personally thing that they are both great dramas and would have loved it if they were extended. Happy watching :)

The main character through live a similar change in the dramas.
And the dramas are about family-cohesion and about murder.

In both dramas, there is a girl who is an expert in one area, Math in Hard Nut and Weather in Otenki Onee-san, who help out detectives solve crimes using their area of expertise.

Dramas about human-cyborg relationships with the cyborgs developing human characteristics & understandings

Both star Ashida Mana. About the lives of children from abusive/unstable homes

Both about teachers going above & beyond for the sake of their students

Similar concept of 'not so usual' interns facing challenges of being accepted in the medical world. Romance, though context may be different, also has similar feel of overcoming hesitations

Again it is done by the same writer and director. There are casinos but also lots of explosions and exotic locations like Jeju, Africa and Las Vegas. Also starring Ji Sung.

It was done by the same writer and director as Triangle. It is a really good story with Lee Byung Hun and Ji Sung and it is all about the world of casinos.

Similar concept, divorced couple get back again.If you like one of them then sure you will like the other.

Both movies share the same intensity and atmosphere. Two loners are brought together by something they share in common, but it's the same thing that could easily break them apart. I wouldn't be surprised if Wong Kar Wai took inspiration from Midaregumo.

Both have the same lead actor with a sweet school love story...moreover both are kbs drama special

Both dramas' male leads are computer genius and CEO/founders of an IT firm.

Both dramas have to do with a parent saving their child within 2 weeks/14 days..
