First time to appear, apparently to fill the plot hole of how Jaewoo got inside the the novel in the first place. Since looking back we never got an explanation how he got inside the story, he didn't even knew if he died in the real world until his memories got back when he saw his best friend got inside the novel to take him back into the real world...got me a bit confused but made my own understanding of the storyline (￣∇￣")
Why did the sister suddenly appear??? Do we saw her somewhere???
