Is this drama based on a novel? 

While it indicates that it's related to Les Interpretes, I was unable to find any connection between the two.

Here is the link to the novel that Les Interpretes is based on.

Also, Shushengbar link (that includes links to both the translated novel and any dramas that the novel is based on) for Les Interpretes

Hi Anandi ; you already got answer before, and in comments section this question was also answered, so you can safely delete the redundant same titled "discussion page" you started, now.  I assume you know how to do so?   I hope you enjoy the show as do those who stay with it! Blessed year to you.
