Need help with romance in my story?

Okay. First, I think it would be hard for Kai not be aware of her feelings especially if she's trying to use her feminine wiles to manipulate him. Despite her being insecure on the inside, she should probably be very y and sy and confident on the outside. Like she's wearing a mask and only occasionally her true self peeks through. Since they both have emotional baggage there should be emotionally charged moments where they open up in times of vulnerability to each other. It's what will inevitably draw them together.
