Aoki Sho is a young man who lost his Japanese parents and was adopted by one of Korea's leading conglomerates. Growing up with his Korean name Kim Min Seok, he was once considered the heir, but was ousted and kicked out by the family after the death of his adoptive father.

Returning back to Japan for the first time in 23 years, Sho meets Kawase Momoko, who lost her father in an accident. Unaware of their shared past when they were children, the two find themselves drawn to each other. However, a series of unforeseen challenges begin to hit them.

Self explanatory.
Both dramas about two women who are the same meet each other. A duet in Blue hasn't aired yet so not much to comment about for now.

TTEOM broke you? Good. Love Beyond the Grave is here to finish the job.
• Same suffocating, otherworldly atmosphere, you never quite feel like you’re standing on solid ground
• FL Si Mu, like Tantai Jin, is almighty and terrifying on the surface, and devastatingly lonely underneath
• The plot is labyrinthine by design: chaotic, overstuffed, everything and nothing happening all at once, and somehow you can’t look away
• No matter what timeline they’re in, you feel their love is doomed. You watch anyway.
• The acting carries what the script sometimes can’t. Both casts earn every tear.
• The aesthetics and costumes are immaculate. The costume team said go big and absolutely did not go home.
• The OST is haunting, almost mystical

Prequel of season 2, duh...
Set in the 1970s, Baek Gi Tae is an ambitious man who craves wealth and power. Jang Gun Yeong is a prosecutor with animalistic instinct and fearsome tenacity. Facing a major incident, Jang Gun Yeong throws his everything to stop Baek Gi Tae. The people around them include lobbyist Choi Yu Ji, investigator O Ye Jin, Bae Geum Ji and chief secretary Cheon Seok Jeong.

Both are BLs with a similar vibe and relationship between the leads - one MLs is involved in criminal or shady business, the other a hardworking talented and upright person.

Both are BLs in which one of the MLs is a gang leader and the other a good guy who finds himself deep in the world when he falls in love.

As far as having a main character who is a psychotic manipulator...these two have such a character in spades. Plus lots of tension and drama.

The plots are very similar and involve psychological suffering + revenge stemming from an incident brought on by a group of evil individuals. The male lead actors' skills in each are very impressive.

Similarities:
1. Both have an ER theme.
2. Both doctors help patients in extreme conditions.
3. In both, the hospital administration doesn't like them.
4. In both dramas, the ML is super good at his job ( TTCHOC ML is top-level).

Difference:
1. There are a lot of scenarios in TTC, unlike DD, which has a whole earthquake scene.
2. In TTC, there is no romance.
3. The ML in TTC have support from the government.

If you like the adrenaline rush from DD, you will love TTC and vice versa. The major difference is that there is no romance in TTC; you will not feel the need for it because it is very fast-paced and has a super charismatic ML.

Both dramas feature badass female characters. The female generals: Chu Qiao and Fu Yixiao are the best representatives we have. Actress Li Meng stars in both drama, too, play a character that previously played by Li Qin.

Female generals rule the world! Both drama feature female lead who are military general. However, in Rebirth, we got two badass female general (Chu Qiao and Huan Huan) and more strong and capable women (Queen Lingyue, Miao Miao, and Ming Lu). Both drama involved "crazy villain" archetype, but in Rebirth every villain is a crazy beast.

Rebirth is a continuation and re-adaptation of Princess Agents. If you still want to know what happened after the Frozen Lake incident, Rebirth has the answer. The story finally ends with a happy ending, creating full watching experience.

Li Yunrui plays the main leads in Rebirth and Blossom. His acting is top nocht delivering complex characters Song Mo and Zhuge Yue. His emotions are well expressed through his eyes. Both dramas are directed by same director.

Similar theme on unity, peacemaking, and freedom from oppression. Minimum romance, highlighting politics and military maneuvering. The difference, Rebirth is a historical fantasy, Swords into Plowshares is guided by historical records. Both are realistic in depicting human suffering amidst chaotic era.

both are enemies to lovers with the trope : the one who will fall in love with the other one first will lose
