Both are gender bender. At first I think, that TB is inspirated by YB, but I found, that it's third remake of thai old lacorn. In TB main hero doesn't know, that she's girl. TB is one of the best thai lacorn I have ever seen, story was well done, quite similar to korean production. I found out TB quite realistic, but there was only one weak point - main evil character and plot around murder.

Both are ones of few really cute lakorns with interestingly developed characters. LN resembles korean drama too.

Same scriptwriter (she has typical own "handwriting") and you will find Sung Joon in both shows. DoR can be INR4.

Same scriptwriter. You can find, that there is same main actress in both dramas.

There is same scriptwriter, so you should expect same atmosphere.

There is same writer in both dramas. WCh is inspirated by north european thriller, WR is crazy korean romance, but in criminal line, you can see similarities.

Theme of baseball is mirror of story in these dramas. 9E2O is realistic then WR, but WR has criminal plot.

Spinster started with dating. Similar embarassing situations (in OMD some scenes are over the top), funny... OMD is shortened +200 drama (2004), so the movie isn't comprehensive enough. LC is far better IMO.

First half of dramas have quite similar atmosphere, similar characters, but second half of SFftS is not so good.
