Both dramas resolve around classical music and a music academy. They both also tackle a plotline depicting characters who are passionate to achieving their dreams.
There are many similarities between the two plots. In Extraordinary You, the female lead finds out that she’s in a comic world where she’s a supporting character with less time to live. Meanwhile, in Romance of Tiger And Rose, the female lead is a screenwriter who accidentally somehow gets stuck in her own script world where, like Extraordinary You, she’s also a supporting character with less time to live.
