Suspense!! And this one is shorter- only 12 episodes! The pacing, OST, and cinematography are equally as good, if not better. Oh, and the production quality is amazing as well.

Not similar story wise but both movies have great cinematography.
Both are with an historical setting and about old traditions.
The Peking Opera in Farewell My Concubine and Yoshiwara in Japan with its courtesans in Sakuran.
Also the movies are more suitable for a mature audience.

Season 2 is the continuation with the setting in the business world after Season 1 played in the school setting.
It also deals with a lot of social/gender issues and has the same style.
The cast is different but once again consists of female leads that support and comfort each other. Gives off the same vibes than the first Season.

Both have sismance vibes and women supporting women, dealing with issues and worries of the characters.
Both include strong female characters and shy ones.
It's Okay To Be Sensitive 2 has business setting, Age of Youth both business and school.
Both dramas give off a comforting feeling while watching because of the strong friendship and support among the characters.

Bungee Jumping of their Own is the original story - Dew the Movie is the Thai adaption.

Although very different in tone and story both are korean mini dramas about a love story between two guys with happy endings.

so the ml has the same personality and practically the same life, minus the f4 part, he's arrogant and rich and finds himself falling for a poor girl that stands up to his bullying, I feel like this is a compilation.

it's the same story and plot, this is an adaptation it just didn't get permission so it wasn't counted as an adaptation

Both of the dramas are comical and are about time travel.
also if u are feeling sad and dull they are good for a laugh

ML in both come to earth and mingle with immortals. FL in both the dramas are doomed to die early in each lifetime
