Bab 618: Yes.

Ryu smiled lightly, reaching a hand forward to ruffle Yaana's hair, but to his shock, he ended up getting his hand slapped away. 

Yaana's pout caused Ailsa to burst into a fit of laughter. 

"If you want, Little Yaana, I can sneak you into his bedroom. He's not very good at controlling what's down there."

Hearing such vulgar words, Yaana immediately flushed red. 

The truth was that she didn't know what Ailsa and Ryu had secretly communicated about, so she was in the dark about the things she herself had done. So, when she saw Ryu stretch a hand forward to ruffle her hair like she was some little girl, she immediately showed some snappiness. 

She knew that if she let Ryu get too comfortable with treating her like a little sister, she really wouldn't have any chance left. So, if there was anything she was determined to do, it was to make sure that Ryu took her seriously. As for what happened after that, she would just accept it.
