- 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

I felt these both were similar because the female lead who is poor thinks the hero is a poor guy in this series too... IT IS A MUST WATCH IF U LIKE THIS .... (rich guy poor girl romance)

The plot revolves around murder mystery and motives behind it, the suspects are close group of friends, also struggle to survival is common though the scanario is different.
In both series, you can see the evil side of human when he tries to survive by abandoning their humanity and values.

Both leads are a little different than your average detective and both dramas are entertaining and fun to watch

Thai, teens, school, drama, relationships, friendship, romance (yuri, yaoi and het), daily life, struggles and etc.

Both feature three males attempting to lose their virginity - only one of which has a steady girl friend.

Both have pretty similar humor

Characters in Explicit Innocence are a year younger (finishing high school) than those in Twenty but they are around the same level of maturity and state of attempting figuring out their lives.

Both ML are cold at the beginning and then change. Both FL are sincere and direct, which is refreshing in dramaland.

There's not so much sci-fi in Hello Monster but it's also about two brothers who lost each other and the mystery/thriller genre is very strong. There's also more romance in hello monster.

Both the dramas are realistic; every character in these dramas is well thought out and portrayed. Also, the story lines are logical and have a strong impact on the viewer.

Both stories are about a body swap.
The main female lead, in the beginning, is interested in another guy.
I think Secret Garden is way more funny and interesting. It also has a more concise plot and clear ending. Its heartwarming with an unexpected plot twist.

humane doctors - wonderful supporting chara(s) - sad but heartwarming case of medic - and most important: there is an onscreen aura of honesty and realness

Both movies is about someone that getting framed for a murder and how they are trying to prove their innocence

same kind of darkness with dosis of violence and sex, zebra is more dark and about ambition and revenge while Double mints is more about a sick kind of love

Both dramas are based on an autobiography of a real-life figure in Japan.
Both are also set in Japan from the past era.
There is also a little bit of story about the effect of WW in Japan.

The difference between the two:
Tenno is about a guy who became the emperor cook, whereas Gegege is about the life of Gegege no Kitaro mangaka from his wife point of view.
Gegege has a longer eps (Asadora) whereas Tenno is short like a typical Japanese drama.

Both are very difficult and thought-provoking movies that explore the victims of Sino-Japanese war and its consequences.
