Alchemy of Souls

University student K is an ordinary young woman, but, one day, she finds herself in her favorite romance novel set during historical times. She has now become the minor character Cha Seon Chaek. She is the daughter of a wealthy noble family and her dream is to have a peaceful and normal life. Cha Seon Chaek, while possessed by K, then spends one night with Lee Beon, the lead male character in the novel.

He comes from a royal lineage and is favored by the King. Lee Beon has a cold-blooded personality and is gifted with an attractive appearance and outstanding martial arts skills. He has also experienced a heartbreaking past. Somehow, Lee Beon and Cha Seon Chaek happen to meet and talk. Lee Beon is consoled by her about his heartbreaking past. They spend the night together. Soon, Cha Seon Chaek tries to connect Lee Beon to Cho Eun Ae, who is the lead female character in the novel. According to the novel, Lee Beon and Jo Eun Ae are supposed to fall in love, but, due to the appearance of Cha Seon Chaek, Cho Eun Ae's fate has changed. No matter how hard Cha Seon Chaek tries, Lee Beon’s love always finds its way back to her.

Other people around them include Jung Su Gyeom and Do Hwa Sun. Jung Su Gyeom is a young officer from a prestigious family. He is Lee Beon’s only friend. Do Hwa Sun is an ambitious woman whose life goal is to marry Lee Beon and become a member of the royal family.

both are costume dramas with beautiful visuals and fantasy elements centering around a female assassin and a man who would do anything for her. the female leads are both incredibly strong women with tragic backgrounds whose desire to survive drive them forward. one difference would be that in alchemy of souls, the fl is the teacher and the ml the student, while in bloody romance it's the other way around. alchemy of souls is also more lighthearted than bloody romance, but both dramas do get dark at points.

The fate of these people become twisted due to "hwanhonsool" (the soul of the dead return to the living).

In the country of Daeho, Jang Wook comes from the noble Jang family. He holds an unpleasant secret about his birth, which people all around the country talk about. He's a troublemaker. Jang Wook happens to meet Mu Deok. She is an elite warrior, but her soul is trapped in a physically weak body. She becomes Jang Wook’s servant, but she also secretly teaches him how to fight.

Seo Yool comes from the noble Seo family. He seems perfect with good appearance, intelligence, and strong martial arts skills. Go Won is the crown prince of Daeho. He hopes to become a generous king.

Samet story of Searching for the missing crown prince, although the story is different. It was Jang Uk, who turned out to be the crown prince, that is, his father's soul was king but his body was eunuch. Unlike Lee Seol, he ran away from the kingdom but he slipped away by taking the test of becoming a soldier.

- Love stories of one of the leads harboring the intention to kill another for their interest but getting entangled with each other by fate that soften their hearts to eventually grow unconditional love for the other.
- Magical settings, formations & powers
-Female leads have another identity that's significant
-Angst

University student, Takatsuki Minato, likes things to be clean and in order while her stepbrother, Takatsuki Toru, is a bit of a player. One day, while cosplaying as a high-school student in a fashionable district in Tokyo, Minato accidentally bumps into Toru and quickly lies about her identity. To her surprise, Toru appears to take an interest in her alternate identity, Mina, and asks her out. Thinking that she might be able to cure Toru out of his playboy ways, Minato continues to disguise herself as Mina but will she be able to keep up the charade when she starts developing feelings for Toru?

It's the same mythological,and eradicating evil to bring peace in the world.
It has the connection where in ancestors of ML's have sacrificed to seal the evil and now the present generation are also fighting it

A tale of love and adventure between an immortal fox and an artisan goddess. An eternal love that will face enemies in heaven and on earth.

I wouldn't say these two dramas are very similar, but here are some reasons why I'm recommending this:

~ Fantasy Elements [Demons/Humans/Mages with Powers]
~ Powerful Lead Characters [Both have strong male and female leads . the ML in AOS weak at first but evolves]
~ Slow-burn Romance
~ Investigation and Mysteries
~ Strong Themes of Friendship and Family
~ Famous and Talented Cast
~ Great Cinematography and Visuals
~ Great CGI and Fight Scenes

The FL is an assasin, she loses her memory and is a 'perfect lady': cute, charming, ...
Alchemy of Souls did it better because it start but building the FL up with her assasin-reputation and slowly revealing she has feelings. And then she loses her memory.
Are you the one starts by having the FL losing her memories, which makes it so we can't connect to her very well

Dear Hongrang similar to Alchemy of Souls is many aspects
• historical
•melodrama
• lee jae wook as a main lead
And without that these drama is filled with thriller and Alchemy of souls was the same
