Tempted (2018)

The basic story is similar, but be carefully "Sai See Plerng" is more emotionally dangerous.
I can't watch it again, because of it. It is for people, who found "tempted" too harmless.
The role of the seducer is played by a woman here, while in "tempted" it is a man. She have 3 Men to play with.
"Sai See Plerng" is not that gloomy. And the first episodes are quite nice.

Honestly the plots have nearly nothing in common, maybe the cuteness of the lovers being together. On the other hand, the camerawork, the colors and somehow the similar classical music in the background made the vibes of THE GREAT SEDUCER remind me of THE K2.

spoiler:
in both dramas love triangle / square is very similar (3 close friends with similar hidden love triangle and new girl in picture, friends fall apart because of her)
though in Brahms there is another old friends love triangle for FL part .

overall Brahms characters have more depth, though as I remember Tempted has also quite promising start with "Gossip Girl" wibes. and also Tempted has more beautiful cast ))))

- Both relationships begin with deception from the male leads
- Both male leads initiate the relationship at the start to use the female leads, but eventually end up falling in love
- The Great Seducer is less comedy, more serious, quality is also better, has a more angst feel

Kanzaki Miwa is married to Kanzaki Hiroki and is a full-time housewife. She used to work for a large company but made the difficult decision to quit her job and become a full-time housewife in hopes of having a child. But her marriage life isn't going very well as her love for her husband has cooled considerably. Hiroki acts like an ideal husband when around others, but he speaks harsh words to her when they are alone. She lives her days like a bird in a cage. One day, Miwa meets her childhood friend Fuyutsuki Ryo, whom she hasn't seen in years. Back then, Ryo was like a hero to her and loved by her. When she was in trouble, he always came and helped her. They make the fateful decision to spend the night together, and Miwa later finds out that she is pregnant with his child. She doesn't want to divorce her husband and become a single mom because she doesn't have a job. To protect her baby, she decides to tell her husband that she is pregnant with his child.

quite different vibes and atmosphere but similar relationships:

in both dramas: 2 boys and girl are close friends from childhood, they were together in good and bad times, supported each other in hard times, always together in and out of school. Girl secretly loves one of the guys (ML) and another guy loves her.
But things change when another girl comes in picture and ML develops feelings to her. Their friendship changes, ML changes...

though both dramas are about high school teens but "Tempted" has more mature vibe and somehow little dark.

p.s. both dramas have light sexy undertone (in "tempted" it's more in "3 friends part" and friend female/ML relationship, in "Kinkyori Renai" it's more light and related with sexy second female (who came later in picture). Overall both dramas have one sexy female )))

Both male leads are playboys who like to seduce and play around without any emotions attached; and they also have complicated relationships with their fathers. They also have a female "best friend" or step-sister with whom they make plans together.

Both dramas deal with the posh youth of Seoul.
Rich heir boy vs cinderella type girl and all the family drama all around.

These dramas are reminiscent of the Gossip Girl series.

This Taiwanese movie and Korean drama are very very similar. In the drama the guy Kwon Shi Hyun makes a bet with his friends that he can seduce the naive girl Eun Tae Hee.She fell in love with him of course and guess what happened when she found out. about the bet??!! LOL I enjoyed it but if you liked this movie than you're definitely gonna like this drama too. Recommended 10/10!!!!!! :)

There main male lead are most a like and famale lead too working hard and flatter I don't know but I find something about irritated so I stopped to great seducer but you mighty like this drama

In both dramas ML approaches FL with evil intentions for personal gain but then he falls in love with her. These dramas are addicting, dramatic and the story is influenced by lies and complicated relationships. Lovers have to overcome hardships that stand in their way.

Both male leads start to develop feelings for the female lead after approaching her for ulterior revenge driven motives. Both are angsty melodramas that play with your emotions.

They don't have too much in common story-wise, but they give off similar vibes. The characters seem unique and refreshing in both.
