Hi seara
Shin Hye has always been hated by those jealous people who find it unfair that she is paired up with so many flower boys. Example, Yoona fans, SeoHyun fans (even though I don't see half the talent these 2 have compared to Shin Hye who is so versatile). I think we are immune to it by now as Shin Hye fans, but I think there are more people who love her than hate her. I mean, 16 million just saw her in Miracle Cell No 7 so she has garnered that many more fans. Also, she has been winning Popular Actress for the past 2 years at the Baeksang Awards and possibly coming back for another one this year (cross my fingers).
There will always be haters for any famous actress. The only reason she is hated is because she's famous. However, If 90%of the people love her, that is good enough. I don't care for the other 10%. Even the nicest and best person will have haters.
