She in reality likes Zatch but her affection comes out a bit differently, she keep on abusing him verbally and damaging his toys and followed by more creative ways of abusing and disturbing him, I think she needs a break from all this behavior and release her true feelings for him.

Her main intentions are to help Killua and Gon develop their abilities to stay safe because of which she puts them on an intense training program which could easily get them killed.
P.s she has no fear of using her real appearance as a young girl to get what she wants. Although she does protects them when they’re nearly about to die or get killed but she wants them to be trained the hard way first!
