Firstly, the synopsis is a little off.
The story is indeed about a young girl, Jing Jia taking her twin sister, Jing Shu’s place when the sister went missing right before the wedding.

Prior to that in a separate chance encounter, she met her sister’s husband to be and attracted his attention.
They got married and the groom’s family has a complicated typical Chinese family background that resulted in them
agreeing to stay together as married couple for their different reasons.

At ep 19; the ML finally realized that the FL is not his intended bride but the twin sister and he was pissed as expected.
However, the conversation was also witnessed by another party in ML family that is jostling for power and has ill intent towards the ML.

I strongly recommend because aside from comedic moments, the chemistry is good between the two leads. The actors are good for both leads. I consider this same as “A familiar stranger” genre… short and entertaining and very good to pass time whilst waiting for regular drama to air.

11May: I have finished the show, the ending a little underwhelming and somewhat disappointing. Don’t misunderstand me : it is a happy ending just not as good as others of same genre…
