These 2 dramas are similar in that it features a modern person who time-travelled to the past. Both have the modern person acting as the wife of a prince and the princes only begin to look at their wives differently after the switch. Only difference is that Go Princess Go features a man in a woman's body and The Eternal Love has 2 souls residing in the female lead's body. Lots of modern references makes the story fun and does not take itself too seriously.

Both dramas feature an aloof prince whose heart is slowly softened by the female lead. Both Sheng Yi Lun (Go Princess Go) and Xing Zhao Lin (The Eternal Love) pull off their roles very well.
