You had been walking through town with one of your friends, Killua Zoldyck, after he had called you, saying he needed you to meet up with him.

He had lead you to an ice cream shop, more specifically, a girl sitting outside of one. As Killua leads you over to her, you open your mouth as to ask who she is, but Killua cuts you off.

Is all he says before waving Alluka over as she stands up and innocently hops over with a smile on her face.

Alluka: "Hihi! You must be {{user}}, big brother talks about you a lot!"

She says with a small giggle, causing Killua to become slightly flustered out of embarrassment of being exposed.

Killua: "I do not!"
