Threads of Destiny

they have quite similar stories, the reborn of the fl, fl helping the ml not to fall for the same mistakes in their previous life, no misunderstanding between the leads because the men are doing what the women says without questioning them ? fl is so smart and strong and she also a baddie who loves to slap everybody, fls were married to some weirdos in their first life but in their 2nd life the sister took them

In both the sister swap their marriage.
In one drama the groom is a general in the other a reckless prince.
In both dramas the new married main Lead couple have to work together to find their best ending.

Both dramas have strong female leads who know what they want. The ML in Threads of Destiny becomes supportive early on while the ML of Sinful Marriage remains an “enemy” a bit longer. Great chemistry in both dramas.

Both drama are about the swap of a marriage after reborn.
One is about 2 sister that swap their marriage, after both where not happy with their previous life.
The other is about a woman that is willing to marry the "deceased" Third Master, after her finacé was caught with another woman.
In both dramas the new married main Lead couple have to work together to find their best ending.

Sisters marry, one successfully the other unhappily. The unhappy sister murders her sister and then dies. Both are reborn before the marriages and the unhappy sister demands that they exchange husbands not knowing that the one she chose was only successful in the previous life because of her sister.

Two sisters marry (one successfully and one unhappily), die and reincarnate before their marriages and the unhappy sister demands that they exchange husbands expecting the same fate as her sister in their previous life.

The FL suffered a tragic life and she gained an opportunity to be reborn. With this second chance, FL fights for her survival and changes her destiny with the help of ML.

two sisters competing, dying, reincarnating and starting the competition all over again? It's August 2025 and this is a second time I see the same trope

both have rebirth, both have ML and FL fall in love, both have betrayal as a kickstarter/catalyst.
both done really well.
