What makes these two dramas similar is the non-conventional chemistry between the leads. In DYLB, the leads are both adorkably introverted which makes their flirting and interactions so awkwardly sweet. In RO, the leads march to the beats of their own drums caring little what others think about them. Consequently, this makes their back and forth banter and flirting so effortless and refreshing to watch.

Both Run On and When the Weather is Fine have a similar laid back vibe with leads that are interesting, well-written and relatable. The secondary characters in WTWIF also make you root for them and add depth to the story.

In both cases, the main leads are connected by the death of someone they care about. In Chocolate, there is a decent amount of push back from the male lead as he struggles to get over the death and accept his feelings for the female lead. Despite that, like in A Piece of Your Mind, he is drawn to the female lead - he seeks her out constantly (whether he realizes it or not), and looks for her when she isn't around.

Chocolate, is however, with an older couple. Probably around a decade older than that in A Piece of Your Mind. There is also significantly more conflict in the show as it is a full 16 episodes. The conflict the male lead has is similar in both (a good throttling solves the issue in both cases (followed by consolidation of course)).

Fair Warning: If You decide to give Chocolate a try, have a box of tissue ready. Though the romance is progressive, there are single-episode stories since it takes place in a Hospice ward (a place where people go before they die). Some of these stories will break you into a million pieces.

Both dramas have a healing theme. The main leads lean on each other for support, and develop their relationship from shared pain. In both cases, a tragedy brings the leads together; it's more immediate in A Piece of Your Mind, whereas in Just Between Lovers they reconnect years later.

Neither drama has a love triangle, which is an added bonus. The romance element is incredibly fulfilling. The longing glances, the words not said but understood, the passing touches.... It's incredibly heart fluttering.

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
