Both movies are early New Taiwanese Wave productions made by Chen Kun Hou-Hou Hsiao Hsien duo with Doze Niu cast as main character. Both stories focus on mundane life of youths and grave consequences of lack of communication between family members

Both shows tell the story of young genius officials who use their smarts to fight injustice and solve mysteries.

same base story. based on the 13 zodiac signs. many of the cast from SSA are there in OME.
I loved OME more!!

Both are typical time travel stories about a young female time traveller and her boyfriend in a fictional ancient kingdom.

Both shows contain showing segments of celebrities lives, however Omniscient Interfering View focuses more on the celebrities manager. Also both shows have host watching and commenting over the segments and contain the element of 'real variety’.

Same high school theme, smart boy, not so smart girl, a second male lead that makes us have second thoughts, kkkkk. This two dramas are amazing, they make our heart skip beats.

Every episode in these two series are like watching movies. Filmed beautifully, complex characters, strong competent leads. There is fighting, romance, drama. High quality dramas.

This movie has the exact same lead actress with the same age gap theme. The endings are kind of similar but close range love ends much nicely.

They both start off similarly. the secondary couple is similar to LCDF. both MLs are nerds and plans to abroad for studies. both main couples are each others crushes for quite a while. the first half of the plot is similar.
the difference is that in LCDF the story revolves around their adulthood while in AIWFLIY the story continues to their collage. though collage life is shown in LCDF its vague.
i overall got similar vibe from both dramas.
I highly recommend to watch LCDF if you liked AIWFLIY. i personally liked Le Coup De Foudre more than All I Want For Love Is You.

Jae Chan in this drama certainly reminds me of Nam Sin III in Are You Human Too? I find both male lead characters incredibly charming in the way they relentlessly protect the female leads. Both dramas also have incredible screenwriting so I'm sure you'll enjoy AYHT as much as you enjoy WYWS.

Female lead’s luck is very bad while the male lead’s is good. They bumped into each other one day and their luck exchanged.

60% similar plot, same era, and costumes.
While 'Blossom in Heart' main business is cosmetics, it is perfume in 'Legend of Fragrance' so even the settings with flowers, etc. is almost identical. The old family secret, lost love, revenge, and missing FL father is the same ( even the actor is the same LOL).

They both involve a group of 30something trying to succed in life (careerwise and relationshipswise) and the different obstacles they must face in order to get where they want to be. Also they both try to destroy the mindset of "when you reach 30 you're too old to do anything new". They're both about friendship and personal growth

There was nothing about fantasy in INR3 but those two, somehow, gave me the same feeling !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

So, I recommend Shin Don only because it has common historic characters with Faith. You'd watch it if you have educational purposes (want to learn more about the period).
