Because both series have similars storyline, the confusion between a woman wear as man, a very good man trying to be king and fix the world. The difference is basic about the second characters, which are more kind and nice in Love in the moonlight than in Shine or Go Crazy.

In both dramas, the protagonist hides his real identity from the girl he loves.

Marriage at the begining, crossdressing, similar clever heroine and similar feeling of these shows, but the end of PC is realy funny.

Both are historical dramas and center around cursed princes that become driven to punish evil in their kingdoms. NWJ has supernatural and fantasy elements

same female leads,
instead of girl pretending to be a male, it's male turned into a girl.
this time the girls work together

Although their genre is totally different .. but they have a lot of similarities .. similar vibe .. both love stories started from * let's pretend we are married * also in both jang hyuk is the lead with his crazy laugh ! .. it seems as well that the female lead in both is kindaf innocent pure-hearted and maybe silly but very hardworking ! Shine or go crazy maybe has a more complicated and serious plot in addition to the romance plot .. but in both we can say that the two are FATED to love each other !

Both involve princesses whom had to suffer due to an oracle
They're both worth watching historical dramas

Both are historical dramas
Both have FL and ML that surprise you with their actions
If you liked one you will probably enjoy the other
