A Korean Odyssey (2017)

Both female leads can see ghosts and male leads are supernatural beings who cross path with the female leads.

The same male lead, both with supernatural elements and a bit of humor ;) And we're going to have romance there :D

It's Fantasy, it has Comedy and the main character was forced to see ghosts. The ML in Korean Odyssey is the same in being stuck, and really old like FL in Hotel Del Luna.

About deities and other creature amongst us, a Korean Odessey is heavy on the fantasy side while Angel’s last mission is heavy on the romance.

I see L as a sort of younger version of Lee Seung Gi, (from the time when he was doing comedy and not thrillers.) I think they have the same type of comedic acting. the story is similar - a deity who does not follow the rules and is a bit of a troublemaker falls in love with a human.

While Angel's Last Mission: Love has less fantasy elements than A Korean Odyssey, it does have a very similar atmosphere. Both have many romantic elements and in some ways a similar romantic plot.

Here there is no angel but a devil. But its fun watching it. It is better than Angel's last Mission.

All the gods will be leaving before the last rain of doomsday. However, an ordinary human girl unexpectedly puts a dent in their plans to retreat thus causing the world to move towards the unknown. Based on the animistic mythology of the Amis tribe, the gods are no longer willing to bless the land that is plagued with environmental issues. One by one, the gods depart the world they once loved. A human girl discovers that the opportunity to reverse her destiny lies within herself and her guardian. Before the final day of judgment, a love story between human and god unfolds.

These shows have similar vibes and depict a strong connection and love between the male lead and feamle that leaves you wanting more. Son Oh Gong (A Korean Odyssey) and Dongfang Qing Cang (Love Between Fairy and Devil) are both badass male leads who are the strongest in their respective world. They can be cold/ nonchalant in their attitudes and are both bond to the female leads which initially is the reason why they can't killl them. Slight spoiler.... Both male leads develop a weakness because of their love for the female lead, but this weakness might just turn out to be a strength, and although the female leads in those shows aren't the most powerful, they are both considered unique in their own way and would do whatever they can to protect their male lead.

Both female lead can see ghost.
Both male lead started out by using the female lead for their own interest but fall in love with the I'm the end.
Both drama had demon/ghost taking over someone body.
Both drama had idols.
Both had badass action scene.

the male lead protects the heroine..the male lead at first very arrogant..the heroine didn't like to burden anyone.later, both of them fall in love...

Both drama are from the same writers - Hong sisters. Both dramas are fantasy dramas . Even though plot wise it's different some character dynamics between the characters are similar. While a Korean odyssey storyline is set in the modern time, alchemy of souls is set in a different period of time.

- The female lead is able to see spirits, getting easily bothered by them and needs the help of the male lead to feel secure/protected, although in different ways.
- A complicated relationship of love-hate mainly from the male part
- A similar "ghost of the episode" format, with the main plot mixed between the main character's quest to get rid/help them
- The male lead was betrayed by someone in the past

When I think about ghosts and mystic things, the first drama that comes to my mind is A Korean Odyssey. Both of them deals with a strong female lead and mystical events with funny scenes and great characters.

Both are supernatural dramas with a similar vibe and somewhat likable antagonists. They have similar themes of immortality and reincarnation. A Korean Odyssey is more on the comedy/action side, while Black Knight is more focused on the drama.
