Recommendations

Both of these dramas follow a romance between a human and supernatural being. They handle a mix of comedy and seriousness while portraying a story with deeper meaning than just romance. They are also both based off of novels, as most chinese dramas are.

Both are set in the office setting, and the leads also share a boss-employee relationship besides a romantic one.

Both are about famous Samurai mathematicians. Both are based on famous novels.....................................................

I honestly don't know why this recommendation hasn't been done after all this time these two dramas have been realeased. Both stories involve a deadly virus that has a 100% fatality rate. The End Of The World is focused more on the medical/science side and The Virus falls more in the crime (and of course medical) genre. Watch both and pick your favorite.

In both of these dramas, a male and female character are connected in some way in the past though their families work to cover it up. The backstories for these characters in both dramas are similar. Both of these dramas have children whose lives are messed up because of adult's greed, but kill me heal me is more political in a way.

1 Has a similar boss/secretary workplace romance
2. ML has been suffering from trauma and the secretary helps him

Its pretty much the same plot there’s also a second season which gives more background info about the plot it’s on Netflix both season.

Romance between a human and non human. Both have comedy and romance. Both are good dramas...............................

Both have the lookalike takes the place of the original one trope.
But are you human too? Has a robot
and I imagine your honor has his twin brother

Firstly both are chinese dramas and negative characters in both dramas are less. Both are feel good dramas. In sweet dreams hero and heroine meet in dreams, but in loveo2o they meet in game.

Both were adaptation of the works of mangaka Shimamoto Kazuhiko. Both were strangely fun and compelling in spite (or because?) of over-the-top acting.

A rebel fights the Japanese tyranny during its occupation of Korea.
Main lead must fight against Japanese officers and Korean aristocrats in both shows.

Both dramas are very progressive and make a social commentary about the struggles women face in and outside the workplace. From sexual harassment to gender discrimination and everything in between. Both are dramas that will leave you thinking.

Both are bl...
There isn't that much similarity between them except the quality of the filming and the language.
I can pretty much guarantee that if you liked one of these you'll like the other as well.

Both are bl and are adapted from a manga.
Both have a somewhat similar feel.
Seven days has been separated into a two part movie tho.
