both are about a sword that can destroy the world depending on the person that wields it. only someone chosen by the sword can wield it.

it's about a power that everyone wants but not anyone can control. in smiling proud wanderer is a specific technique and in myth of sword its about a sword.

about a sword that everyone wants but now anyone can control. one is more political and the other is more about the martial arts world.

the story has a mystery and it is unravelled as it reveals itself you come to have a better understanding of the characters

they are looking for something that gives power and has been lost for a long time. the bromance between the 2 male leads is both interesting and amusing too

The only similarity is that they are reincarnated lovers and both think that the other one destroyed their family.
Both dramas are very very different from each other except the reasons above. While bulgasal is a revenge, suspense, thriller drama with a little bit of Melo and romance, "from now on showtime" is a rom-com, lighthearted drama with some ghost and revenge plot.
But both are very interesting drama. Even when Showtime is still on air i recommend it cuz its not looking like it will disappoint it's viewers, and am loving it do much.

In both dramas :
- Rich male Poor female
- Married Couples
- Misunderstanding between the main leads
- Short length series

Both series include a main character whose parents die, he is then adopted by a new family and later falls in love with his stepbrother. One of the stepbrothers in each of the series initially refuses the other brother's affection because he does not want to disappoint their family but after some time he surrenders. In both dramas, the parents refuse to accept the relationship at first, so the couple has to persuade them that there is nothing wrong about that.
HIStory4 has a darker vibe because one of the characters uses morally questionable means to get his stepbrother's love.

Best Time is the original series. If you want to know the original storyline of this special you must watch the series Best Time.

Both dramas are based on deep-seeded past family revenge plots - carried out by a daughter in one series, and a son in the other drama. Both children set-out to take revenge on both of their father's enemies - their targets the families of those enemies. One target family has three brothers, and the other has three sisters. In both dramas, the siblings are apart of the plot.

Both the dramas On the way to the airport and where stars land are based on airport romance mainly Incheon Airport
Both dramas have naive FM
I somehow get the same vibes from ML
OTWTA is a slow paced adult romance with cheating story involved

The story is kinda same, deal with the time clock and how much time to live.
-FL can see people clock time to leave even her owns (about time). FL lead in don't be shy she can see her own only.
-ML can stopped the time clock.
- Both leads hate each other at first then they eventually become close.

Strong woman character, ambitious, hardworking, friendship and women empowerment.

"Pride And Price" tells a motivational story of women in the workplace who have gone through a variety of workplace rules and job tests to defeat their competitors and set off their dreams.

What if Theo's love language was physical touch? What if Fiat didn't have trauma?

Don't Say No is more mature in tone and subject than Enchante (which is primarily a romcom). But both BL stories focus in on a main lead with abandonment issues and a presumed unrequited crush on their childhood best friend. Both of these leads go to questionable lengths to make this crush jealous in the hopes of making him take action - fueled by their reluctance to take action themselves as a result of their fear of abandonment. Furthermore, both plots are complicated by "love rivals" with agendas and discuss topics surrounding changes in family dynamics.

Suspense , agony , phycological pressure , palace politics and battling to survive inside the palace and save your soulmate from death....
Those 2 dramas are identical. Action , suspense and romance all combined.

Great cinematography in both dramas.
Every episode ends with a cliffhanger and leaves you wanting more.
