Cain and Abel (2009)

Subtle biblical references, relationships between brothers, extreme situations that make characters go through emotional crisis and very tearful melodrama, all the ingredients are found in both dramas.

It's very similar, involving hospitals, brotherly feuds, and the deep sense of revenge.

Based on the biblical story of Adam and Eve's first two sons, Cain and Abel is about Cain's jealousy towards his brother Abel. Lee Cho In is a very gifted doctor who has everything that he wants whereas his older brother, Seon Woo, is jealous of all the attention that Cho In receives. Seon Woo blames his brother for taking everything good in his life away from him. Seon Woo blames Cho In for getting their father's love, getting more recognition as a doctor, and for stealing the woman he loves.

Japanese Cain and Abel is an adaptation. I've started to watch the korean one and just cannot stop. The stories are different, but the essence is the same.
Two brothers who love each other started to hate because of envy and jealousy.

The story unfolds really nice and slowly. One step after another. There are many surprises during the drama, but they are solved slowly, step by step. Also, great character developing and acting. Be sure to have tissues right next to you.

Both have a classic melodrama story about love triangles, revenge, and complicated relationships between brothers.

In both dramas, the main character is a kind and caring doctor who's deeply in love with his girlfriend. Through a series of tragic events, he is betrayed and loses his identity as an upstanding and respectable man. The story follows his revenge with a family divided by power struggles over the ownership of a company. Both dramas are classic melodramas with tropes like love squares, amnesia and illness.

So Ji Sub as an angsty melodrama male lead who meets a poor but plucky girl working as a tour guide in another country. Things get complicated when she arrives in Seoul and they are reunited. Lots of tears from the female lead.

A major difference is that Cain and Abel has firmly established couples by the 2/3 mark that you will root for while What Happened in Bali keeps the love square unresolved until the very end.

Both are medical dramas about 2 brothers who are neurologists (one of them is adopted) and the competition the face over the woman who they love and their father's admiration

about vengance and family and how you re own family can hurt you without any clear reasons

The plots both involve Surgeons (althougn not heart but instead the brain) and North Korea.

Em ambos os dramas os irmão são médicos e amam a mesma mulher. Os conflitos que envolvem o triângulo amoroso são semelhantes.

Both have scheming families with an evil stepmom and sibling who gets in the way of childhood sweethearts. The star crossed lovers are separated by studying abroad, amnesia, car accidents, and terminal illness. Shin Hyun Joon stars in both dramas as the second male lead who wants the amnesiac main character's memories to stay forgotten. Their love is selfish but you can't help but feel a bit sympathetic. Choi Ji Woo in Stairway to Heaven and Han Ji Min in Cain and Abel are phenomenal at crying scenes that make your heart ache for the female leads.

Stairway to Heaven has a female main character who's in a love triangle between the childhood sweetheart male lead and the second male lead who's her non-blood-related brother. The stepsister played by Kim Tae Hee has extremely evil-looking acting with bulging eyes.
Cain and Abel has a male main character who's in a love triangle between the childhood sweetheart female lead and the other female lead who's his non-blood-related fake cousin. The adopted brother played by Shin Hyun Joon has extremely evil-looking acting with hawk-like glares.

both tackle the hardships North Korean defectors go though trying to adapt to the life in the South.

Em ambos os dramas há a disputa entre dois médicos pela direção da sucessão do grupo e o cargo de CEO. Ambos há disputa dos protagonistas pela mesma mulher.
