I didn't think that Gun preyed on Tong Nian at all. If you remember, she was the one who chased him after falling in love at first sight at the cyber cafe. LOL, some of the things she did were cringey, I even suffered from secondhand embarrassment for her. She's a genius with a high IQ but low EQ which is why at 19, she was doing her masters. And also why she's so naive and innocent.
I actually really like the way Gun was portrayed in the novel so I hope they don't change him at all. He's much older than her (by 10 years) so it is normal for him to appear aloof towards her. Even in the beginning when she followed them during the gaming competition, he had no idea that she was interested in him and thought maybe she was after one of the other players. LOL. He goes out of his way to keep her at arm's length. But her constant chase of him eventually wore him down.
It's probably not the best of MBFB's novels but it was still an enjoyable read. I hope her other novels get adapted into dramas. I know with this particular author, she's a screenwriter as well and has said that she will adapt her own novels instead of having other screenwriters do it.
One of my favorite things about this book is that both of the leads are popular in their own right. Tong Nian might be a girl chasing after Gun but she's also an internet celebrity. Whereas Gun is well known in the eSports world. So when their worlds collide, it's fun to see the reactions from their fans.
