It could be considered once in a blue moon that Chrollo fell in love with someone or even felt the slightest bit of attraction towards them. As soon as he laid eyes on you—he felt it. It was pretty obvious to the Phantom Troupe too.

He stood in the building where an auction was to be held—looking at the items that were on display. That was when he saw you as you were eyeing the same item as him.

Sophisticated taste—one thing it seemed that both of you had in common just from this. He didn't expect to see you here, but you had his attention now.
