The plot is simple : a modern womanizer travels back in time to find himself in the body of the 4th young lady of the marquis's mansion. Now what? Evidently the struggle is for him, to find his way back to modern times.

Big problem : this lady has a male thinking voice. So I was confused to see her getting closer and closer to Male Lead. How could a womanizer get seduced by a man just because he traveled back in time and he is kept inside a woman's body? Will they kiss? Will they consummate their marriage? Is it BL?
To me this plot point seems totally unlogical . So I decided to wait until the last episode to get the answer to all those questions.

On another note.
The plot is well written and there is a lot of twists and turns to this story. I never felt bored and I liked to follow the steps of Female Lead, where ever she was going to, in order to complete her tasks.
The entire cast was good and I liked their performances.

Generally speaking I would recommend this drama because it was very entertaining.
