Gentleman Thief (2019)

FL is also a princess, who will be the crown princess later in the story.
ML is a soldier and bodyguard to FL, who will protect her all the way.
The main differences are that SJJ is a period drama and its characters have some supernatural power as far as its aired episodes.

The long lost twin brother who was raised and forced to become a bandit. The stories are not relating except the male leads were raised separately.

Both ML are soldiers and got the job to protect the FL.
In Both there is a misunderstanding between FL and ML.
In one FL is a princess in the other a physician.
Both are series. One about twin brothers. The other about soldiers friendship.
I like the acting and would say everyone who like military should watch both.

In both the ML get the job to protect the FL. The first as soldiere the other is ex-soldiere.
In both dramas, FL and ML get to know each other better and fall in love. But there are a few obstacles in there way to happiness.
