Empress Mun-Hee Yi is dying of cancer. And for the last twenty years she has been living in Manhattan, NY after seeking asylum for her and her four-year-old grandson Ji-Sung Yi since her husband and Ji-Sung's parents were assassinated by her nephew Eun-So Yi in a coup to take over the throne.
Since learning about her illness, Ji-Sung has been helping his grandmother with her bucket list. There were just two things left. Number 99 is for them to return to their native land, and number 100 is that she wants to be buried beside her husband Emperor Si-Woo on the grounds of the Blue Palace. As luck would have it Eun-So Yi is executed for his crimes but Ji-Sung hopes number 100 won't happen for a long, long time. Unbeknownst to him, Mun-Hee has another thing on her listâ€¦to see that her grandson find love and to settle down.
