Amantes do Mundo das Fadas (2020)

It has a similar vibe in that they are both dealing with a "case of the week" sort of story of people who have died. One of the leads in both dramas is also an immortal sort of character. Both fantasy dramas with interesting plots and have parts in the past and present!

-In both the dramas modern life is connected with the ancient story.
-Both involve supernatural powers.
- In both the ML have a long life.
-In both the ML are in search of FL.
-In both the FL gets incarnated.
-In Both the dramas FL doesn't remember her past life.

Like kim shin, Bai Qi is a supernatural being who has lived for a very long time helping some of the spirits. Many years later he meets the reincarnate of his lover who is also silly but cute, like Ji Eun Tak . Also the relationship between Bai Qi and Yang Jian is similar to that of Kim shin and the Grimm reaper in that they are enemies but do not go as far as killing each other although I am not sure what happens in the future.. All in all, the similarity is in the reincarnation, spirits/ghosts, romance, frenemies, rich man poor woman and the male lead wanting to protect the female lead while being in denial of his own feelings for her.. Not to mention the similarities in Kim Shin's sword and Bai Qi's umbrella. Awesome story so far..

Seems similar in that both have a human general who gained powers and lived to a more modern era. At this point I'm gonna assume the FL in TYFY is the reincarnation of the goddess who gave ML his powers by sacrificing herself which is in a way similar to how FL in Fairyland Lovers gave ML the bracelet... allowing him his more unique abilities.

ML is a supernatural doctor...
ML has been waiting for the FL for a long time after he lost her in the past.

The ML is from another planet and has lived for thousands of years searching for their long lost love. The FL is a re-incarnation of their lover in modern times and is completely oblivious to this fact.

In both, ML is seemingly an immortal. Romance between immortal and mortal. FL is also seemingly a reincarnation in both.

Yuan Zhong is a fox high priest. He is an immortal who possesses the divine hand. With it, he defeated the ghost clan and brought an era of prosperity. Jin Tan Yin is an artisan goddess who makes magical artifacts. She descended to earth to kill Yuan Zhong and get back the divine hand of the god Tang Hua. Yuan Zhong is harassed by his own fox clan and Jin Tan Yin decides to help and protect him. The two of them will have to face personal enemies, and a secret will be discovered. Yuan Zhong rescues Jin Tan Yin from a trap. Reunited again, the pair of lovers join forces to defeat their enemies and restore order in the world.

In both shows, the female lead lives alone, with an absent father, running away from his debts.
She gets to cohabitate with the non-human male lead. And while discovering his magical world, they met other supernatural people and help them.

Similar points:
-ML from another planet
-FL actress
-Both of them (FM and ML) somehow have a past
-Both MLs have powers

Both drama contains supernatural romantic materials.Well, even being a fantasy sci Fi "My girlfriend is an alien" basically focus over romance .Lots of kisses and sweet jealousy scenes.Also slight fantasy materials.Amounts of humor is huge.
While alongside romance and comedy Fairyland lovers contains mystery materials.Both are worth to watch

-if you're into trying a c-drama it's similar to MPUB in those fantasy vibes
-there's a magical adventure and characters that possess magic in some way and are not actually part of humans
-reincarnation plays a huge role!!
-the plots are super interesting and all the characters really make it interesting!

The male lead both have a very long life due to 'something' they are trying to break out the mystery. There's also Estelle Chen.

Both have alien species on earth, and trying to live like humans. Similar modern setting with flashbacks to past era times.
