From the experiences he got in his last life -his own and what he observed from others- Yang JIngshen had realized one fact about these so-called fans. That most of the time, their affection towards their idol was superficial.
In their eyes, their favorite artist should be similar to the image he/she represents on the screen, even in their real life. If they portrayed themselves to be brave and straightforward, then that was what they should be. If they came out as gentle and sweet or cute and lovable, they should be that. And if they had a bad boy or bad girl image– well, that should also be how they act in real life.
