Both involving death & supernatural,
with message about how little time we have and that we should spend our time meaningfully and not take life for granted.

49 Days is one big 20 episode story arc with 1 main lead about to maybe die,
while Loss.Time.Life is more easily and quicker to watch stand-alone episodes/anthology series with 1 new person dying each episode, providing beautiful story even if you just watch 1 episode. (Episodes can be watched in whathever order since each episode is 1 separate story with different characters in each episode.)

Both about the injustices behind news reporting. Argon is more exaggerated and about corruption while Fake News more realistic and highly true to life in our internet centered times.

Lookalikes/twins who swap places as the major plotline and fun part that drives the story in both.

Rud Nee lakorn's main genre is romance, while Switch has very minimal to no romance (the leads banter cutely but goes nowhere) is more law genre.

Both have Multiple strong female leads & Sismances in focus.

Angel Destiny is a severly under-noticed drama with great writing.

Multiple strong female leads & Sismances.

Great writing in both, but Angel Destiny has even better writing.

Both set in the near future, advanced technology that interacts with and changes the human experience in different ways.

Dystopian fiction.

Both Youtube dramas free for all to watch, I really recommend both short dystopian series.

Both dramas are about news stories.
Argon focused on the workplace & politics in a news station and anchors,

TimeLine is more focused around the news stories themselves, and features REAL news stories and not fictional ones.

Both are workplace dramas about journalism, Argon about a news station and Big Issue about magazine journalists.
No romance in either, both centered around the boss-employee relationship between male & female lead.

Modern Royalty concept + Romance in both.

TheKing:EM Also has fantasy element of pararell worlds and timetravel

K2H has no fantasy element

Both have the Modern Monarchy concept + Romance with a king/prince

The main difference is TheKing drama has also timetravel & alternative realities fantasy element too, Goong has no fantasy element

Historical (sort of) + romance

CR is a cdrama set in chinese republican era (early to mid 1900s)

TheKing the modern monarch concept set in present time

Very similar feeling watching both, stunning cinematography & visuals and a romance with an aristocratic charming leader (king /ring leader )

Totally different plots,
but

both ACTION DRAMAS with comedy & not too serious with an IMPRESSIVE MALE LEAD WHO HAS BOLD and difficult PLANS.

Both have main themes about REDEMPTION, FALL FROM GRACE and trying to correct a big failure and stand up again

Same EXHITING FEELING and vibes when watching both, never boring

Both have great cast & acting.
