Both very well-written Crime/Action + Romance dramas, with leads with strong chemistry.
Healer has much more romance in focus than Vincenzo.

Both male leads are mysterious/a secret identity kept from other characters, iconic role for the actors.

Anti-hero Male leads (Mafia lawyer & Conman) who team up with a smart Female Lead lawyer to take on injustice/corruption with stronger means than the usual good guys.

Both Crime Comedies with a small hint of romance between two leads with great chemistry.

So essentially same plot but different details.

Very strong satisfaction/catharsis in watching them tackle corruption, really Fun extreme Methods or even laugh aloud funny sometimes.

Both about a group of young adults who live together, friendships and a feel-good mood.

One a drama, the other a variety show, but similar vibes, both are very healing and relaxing and fun relationships.

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
