Both are well made romance movies. They are my favorites even now. Haven't seen a movie better than these 2 for me so far.

They both are detective role plays and both super powers. You might like The Four because it doesn't have a tragic ending like Swords of Legend did.

They have the same Lead actor. In both dramas, So Ji Sub is a man from a rich family even though their attitude and their stories are totally different. Both of the drama genres are comedy and romance but The Master's Sun has a supernatural vibe to it as well. Superb acting and chemistry in both dramas ( even though So Ji Sub's acting has improved so much more in Oh My Venus)

Breath is also about visiting someone in death row. Breath is an art movie, simpler like a dance. An expression of her emotions, a beautiful reaction to her husband's infidelity. Directed by Kim Ki-duk.

Both of them have Joseon kings falling in love with girls from the future and both of them have time traveling elements. The big difference, however, is that in Rooftop Prince, the king gets to travel to the future while in Splash Splash Love, the girl gets to travel to the past (Joseon). They are also similar because of the reincarnation/past life elements (people from the past are also in the present time but have different identity).

a lot of things are happening in the beginning. but all parts will make sense near the ending. both are really awesome movies

Both are completely different amazing movies. However, they leave you with the same kind of feeling.

The movies are different but they're both set in the past and friendships play a big part in them. Not to mention these are both wonderful films.

'That Winter, The Wind Blows' is a 2013 remake of this japanese drama.

Both are really intense medical dramas. Both dramas have a similar feel to them as they both have similarities in them.

It's another spoof or parody of lakorns. Both are supposed to be more funny then dramatic.

The same kind of boy band meet girl idea. The main male lead has a love/hate relationship with the main female lead.

Both is about a divorced couple meeting again after a few years with the girl needing to plan for the guy's wedding with a new woman but the divorced couple still has feelings for each other.

Chan William is in it as the supporter. The plot is similar where the main character have evil aura that could cause uncontrollable destruction. Both male character must be able to control the evil within them.

In A Good Way is not a Korean drama (it's Taiwanese), not set in high school (it's set in college), and the focus isn't completely on the romance, but the same theme is at the heart of both dramas: friendships, relationships, and growing up. Both shows are set in the 90s and explore the lives of their characters as they transition to adulthood and go through all the trials and tribulations that come with that period of transitioning and figuring out friendships and relationships. They both portray relationships with incredible realism, fully develop all their characters into real, flawed, multidimensional people (no real antagonists here), and create these day to day slice-of-life portraits that are full of nostalgia and happiness.
