Alchemy of Souls

amazing chemistry between the main leads. Fantasy+ historical (both are costume dramas), they both have strong female leads. There is power struggle in both dramas. In both dramas the main couple is willing to sacrifice themselves for each other. In both dramas a close family member of the fl is killed and she wants revenge. In both darmas the ml is the son of a king. In both dramas the romance is developing not that slowly but not that quickly as well.

Both FLs are powerful and skilled in magic, and end up transferring their souls into the body of a weaker, powerless girl. The original body is burned, and then end up aiding the ML as well as being under his protection.

Although they are from different countries (one is Korean, the other Chinese), I have to say both are masterpieces. The fantasy element is what really stands out in these dramas. The acting is top-notch in both, and they share common themes such as mystery, powers, romance, friendship, strong lead characters, and humor. If you liked one, you'll undoubtedly like the other.

A love story between the half-human and half-vampire Seon Woo Hyul, who was unable to become human due to a one-day difference over 100 years, and Joo In Hae, a woman who has no humane side and finds true warmth.

Both drama show the ML becoming powerful and mastering their swords! Both characters are witty and do their best to protect the people they love.

In both Fake Princess and Alchemy of Souls, both the FLs work for High ranking families( in Fake Princess, for Crown Prince in Alchemy for Royal family Mages)
Similarities:-
1. Female leads are replacements to the original characters
2. Both come from a village backdrop/ country
3. Both possess fighting skills( In Fake Princess FL being a Mountain Bandit & in Alchemy FL being a Trained Assasin)
4. FLs are smarter than MLs
5.Both FLs have birth secrets
6.Both involve the FLs hiding their secret identity

Differences:-
1.Alchemy is more about magical, mystical elements (like WUXIA) while Fake Princess is a light hearted Rom-Com
2. AoS has a second ML( major SLS alert) unlike Fake Princess
3. In Fake princess, ML fights his brother for the throne unlike AoS

In both of the story the ml is weak at first and will become strongest among the mages/counters
Great teamwork and friendship+ you will get Yoo Jun-sang (park Jin) here too ?(kind of same father figure and one of the strong character, he's friend of ml's father too )
Both ml grew up without parents
Both storyline follow hunting evil soul or soul shifters and the soul shifters/evil souls feeds on human soul
TUC doesn't have much romance and more action based show and set up in modern times
Though it can't beat AOS in storyline, production and fantacy, TUC is still entertaining in its own way
Yoo In-Soo is in the 2ns season and a silly counter friend of ml
If you enjoyed AOS hope you will enjoy TUC too
