Both have similar vibes and a sweet romance that transcends class (and time) along with palace intrigue and dangerous enemies.

Both similar in how there is romance between one non-human and human. Although in IANAR the FL is pretending to be a robot.

Both the movie and the drama revolve around a similar concept of time travel where the guy is an year in the future and the girl and guy fall for each other.

- both are revolved around people in high school / school
- characters who have special abilities
- both involve supernatural and fantasy genres

Both of these are historical romance dramas with the palace life and relationships. They both surround a fallen kingdom and a sole heir are to the fallen kingdom. They both have a female heir getting entangled with the current ruler which leads to conflict of emotions. As I am still watching I can’t say the endings are the same however it’s nearly the same plot with different actors.

Both are the stories about Hong Gil Dong. Main character fights for the poor and opressed while stealing from the rich.

xx SPOILER ALERT xx
In both shows FL seems to fall for the guy first, but acctualy it is the opposite.
I really enjoyed the fact that they made Jiang Zhi Shu (Irie Naoki) fall for FL first in this version of one of the most adapted manga, Itazura na Kiss.

Both movies are about criminal justice. The victims were forced to acknowledge their crime which they had not done. Besides this, it also talked about a lawyer overcomes a lot of hardship to clarify the crime and catch the real criminal. Both these movies are so touching.

Same storyline yet different in levels of heartbreak and acceptance between the leads. Both films deliver and will surely make you ugly cry.

In which their love transcends time and space that they cannot forget the love that they once cherished after having lost the one precious to them.

They both have reincarnation of characters. Lots of flashbacks and stuff. They both have a mystery vibe.

Both have actresses female leads having issues with fame and its problems. They both are airheads while the MLs are more calculists

The two dramas have same kind of easygoing feeling. Love is Deep is more mature but still very light. Both stories are told kind of unique slice-of-life way.

the 3 girls in Be Melodramatic and It's Okay To Be Sensitive drama have a similar "vibe" between their characters...

I don't know exactly but one show reminded me of another:
Both MLs are not much experienced, they're "inoccents", while the females protagonist act cold and indiferent about they bodies due to some kind of sexual harassment in the past.
The male leads care much even if unconscious for the FL.
While Everythig and Nothing have a sad and mysterious atmosphere, HG'sL is more comedy.
In Ho Goos's Love FL gets pregnant .
