This Thai version is a remake of the Chinese one. Boss and employee relationship, office romance, warm FL/cold ML, etc.

There is a similar relationship between male and female leads.
The main characters have unusual characteristics.
Both groups of main characters feel like a family.

Both involve a masked hero that defies the system. Both are action oriented. The Bridal Mask focuses more on melodrama, while Kaitou Yamaneko is more about (black) comedy.

I saw similarity in the two in that in KC the ML seeks revenge from FL bcz he thinks she kills his fiance and in MBJ the FL thinks the ML is the cause of her father's death. Both go from hate and misunderstanding to love. Both are very great dramas!

Both MRA and MBJ are similar in that the the ML is a widower with a kid. There is interaction between FL and the kid which is super cute motherly love. in MBJ ML has a daughter and in MRA he has a son. Also in both we see the development of a family super cute!

Both of these dramas feature a character getting stuck in a fantasy world or a fantasy character getting stuck in the real world.
But have romance, both have cute side characters, and both have open endings.
Pop Out Boy is a light, cute, webdrama while Memories of the Alhambra is a bit sadder and was aired on TV.

Both Pop Up Boy and Lost Romance deal with falling in or out of a fantasy world.
In the case of Pop Out Boy, the ML is thrown into the real world. He used to be the MC of a comic book.
In Lost Romance, the FL is thrown into a novel.
In both of these, one character loves the other and is constantly rejected. However, they eventually melt the hearts of their partners. Both of these dramas also use the plot of "running out of time" in their new world. They also use plenty of comedy which is always fun to watch!

It has a surprise plot twist in the end in regards of the guy that gets the girl. If you want to be fooled into thinking you are getting second lead syndrome then this is the movie for you my friend. In fact, I found this movie because of a recommendation that i saw on the recommendations page of "4-gatsu no Kimi, Spica". And they are indeed similar script-wise. I hope this is useful to someone.

Both have that whodunit story that will make you distrust (or at least be suspicious of) every character. Although they have a different plot, you'll feel the same frustration of not knowing but you would still want the journey of how things will play out.

The movie "Only the Wind Knows" is a Chinese remake of the web TV series. Both have the same native name and both are adapted from the novel of the same name.

Although Haechi is a bit darker, both dramas involve the fight for the throne, they have strong female leads, comedy, romance, and a great story that keeps you clicking the next episode.

Both are historical dramas with strong female leads. You end up loving the main characters as well as the side characters and feel invested in their stories. The pacing in both is fast and you are hooked. Also, SO MUCH BROMANCE.

These dramas both feature a couple going back in time to the prime of their youth after a tumultuous life in their late twenties.

Both of these dramas feature unrequited love by the FL where the ML has no feelings for her. Both of these have really crazy plots (in a good way).
Both have the ML having some sort of trouble with other females, and both have SML's who are really nice.

Both of these are pretty great medical dramas. Emergency couple has a lot more of romance going on and family drama. Golden Time really focuses on just the medical genre but if you enjoy full on medical dramas, this is a good one! I found that the attending physician in Emergency Couple and the Professor in the Trauma Dpt. In Golden Time were so very alike! Both of these dramas involve the E.R, hospital politics, and interns getting into trouble and learning. I love them both and hope you will too!
