I've been following her dramas since The Romance of Tiger and Rose, and I'm really happy that she got a lot more…
Mostly they hate her because of jealousy. With very young age she is already shine and they afraid she'll steal limelight from their idol so they believe anything which they can called 'reasons' for their hatred. And she soo lively and lovable with any her ML so they afraid their idol will fall for her too irl
