Both dramas are psychological thrillers with aspects of family story, sisters' relationships, manipulation and references to backstory.

In both them, the leads lose there wealth are start from scratch again with the support of their families is so beautifully portrayed that you will fall in love with both if these dramas.
Destined is one of my favorite drama and I feel the overall atmosphere of Blossoms in Adversity resembles Destined.

better version of story
husband isn't cheater here, no affair but killer ( serious)
something real husband is a murder here
wife don't have lover to depend but a female best friend,,

Both start with a innocent and naive lead (FL in SF6 and ML in SF4), and they have some mysterious power, which resonates with the other lead. Both belong to the Sword and Fairy series but the stories are not connected, so feel free to watch them

Both the plots revolve around secret crush on a close friend, while one is around college life of young adults other is about highschool romance.

Welcome to Samdalri too revolves more or less around three sisters and their family. Although the two dramas are not that alike, they share similar themes of second chances, family, and community.

It's not exactly similar but somehow a bit part of story is similar ..The ML's father is suspect to murder FL's mother and leads are childhood sweetheart.

~ This story is also about time travelling
~ The protagonist fall in love with eachother
~ They change their future
~ Interesting storyline
I personally think these shows are quite similar as they include same genre

• The plot is somehow very similar
• The protagonist will time travel to save ML
• May be they will change their future
• And obviously they will fall in love
Hope that this helps cause as I saw the trailer i suddenly remembered about marry my husband and the similarities between these two shows

Both dramas are psychological thrillers with aspects of school life, family relationships, touching on themes of manipulating people, a mysterious female character with similar plot twists.

In both of these gay fantasy romances, a connection forms between 2 men living different lives, impossibly connected by the writings of one/both.

Both of these are BL fantasy romances involving the two male protagonists seeing each other through a mirror.

Both about esports and being a professional esports player.
FIYS has romance as it's primary plot though
TKA's game moments like the actors are the players in the game, like they are being sucked into the game and actually fighting, meanwhile FIYS is more obvious that they are playing a game but I think the animation in FIYS is best and it has better fight scenes in my opinion.
Both leads are incredibly attractive

The stories are set in the same universe and have a FL with superhuman strength that's inherited through the matrilineal line

They are similar because

-Both FLs get stuck in a novel
-Similar dynamics between the FL and ML
-Both ML didn't trust FL in the beginning
-Both shows are somewhat comedy centered
-Similar endings
