Recommendations

Both Japanese movies with a psychopath as the main character. Plots are different but with similar elements. If you liked the other you will be sure to like the other one too.

Lesson of the Evil Opening chapter is background information to the actual movie.

Both characters have doppelgangers.Both are melodramas that are a little dark.

it is same exact story line my love eun dong is the Korean version of jai rao which a thai drama

Even though the settings are different, I found many similarities between the two dramas:

- A cold, selfish but brilliant man becomes in charge of a group of people
- A sweet, warm-hearted girl falls in love with him
- A kinder second lead pines after the girl
- The dramas concentrate on the lives of the group of people also rather than just the main couple (more so in Beethoven's Virus, I think).
- Main lead makes decisions for the group that others don't approve of, causes drama
- Main lead slowly earns the trust of the members creating a more united team

The only major difference I saw was that there wasn't as much of an emphasis on romance in Beethoven's Virus as there was in Pasta.

Both dramas are about second hand book stores. This one is also about 'solving' crimes which are based on and surround by books! =]

There are similar recommendations already but I shall include mine anyway. Both dramas have damaged male leads, females trying to heal them and lot of psychological stuff. There's comedy and romance in both too. Watch one if you liked the other/

A less-than-human-becoming-human journey.

One of main characters in both movie and drama is a very similar dark (scary, but also kinda... cute?) psycho with some deep issues and history of psychological (mis)treatment. Both stories show us a lot of violence and you can't really figure out the psycho character till the very end.

Difference between these two is mostly that Bad Guys is a drama and not a movie (so not as short and has more story parts intertwined) and has other significant and complicated characters aside from the psycho.

Although there are serious differences in the story-lines, both are based on a female actress in the modern day being in love with man from another place. The main difference being that one place is 300 years in the past for Queen In Hyun's Man, whereas the leading main role from You Who Came From The Stars was an alien. Both romantic relationships are of equal levels in sappiness, comedy, adorable-ness, and satisfaction. Thus if you loved Queen In Hyun's Man I suggest you watch You Who Came From The Stars because it's another fantastic romantic fantasy comedy.

Both happen in high school, they're both "gender bender" dramas and they're both really funny and adorable. And the acting is great!!

Both are about really strong wealthy male leads that are simply combobulated by the thought of them falling in love with a... how'd you say... peasant? Lol jk

It is exactly the same idea. The only difference is that a guy's wife and his female colleague are the ones who swap bodies. Even though they're basically the same, you'll find both of them very entertaining.

both of them have similar story of double Identy or Twins hhmmmm amazing soundtracks, nice actors, a lot of misterous to solve

same light stories. also comedy romance. altho sweet sweet bodyguard has more comedy moments.
kinda long 82 episode long but its worthwhile.
similar is also one of the couple also involves a kid.
