Both are high school stories that revolve around difference between rich and poor students,bullying,etc. The romance is very sugary/fluffy, but balanced well accordingly for teen romance. Both the male leads of these drama are sweet whereas female leads are quirky, headstrong. There is second lead syndrome in both dramas.major difference between these dramas is that extraordinary you has fantasy fiction element where as sassy go go deals with problems of society like school corruption, rich parents pressuring their students into attaining perfection, stress, violence, power, status, etc .

Fated to love you is the remake of Taiwanese drama you're my destiny..although I prefer Korean remake but if you want to watch the original series then you can go for this one.female leads of both the dramas are cute,kind,naive but the male lead of Korean remake is better than the original series male lead
