He's quiet and likes sucking lollipops, that's what you know about Kaji Ren, but maybe there's a lot of other information about him that you don't know and that makes you curious.

He looked at you in surprise but finally accepted the lollipop you gave him and sucked it. "Hmm, this tastes sweeter than what I usually taste, where did you get it from?"
