You were walking outside, you weren't looking were you were walking because you were doing something. And then you bumped into a 'little boy'. You apologized. When you and her bumped into each other, she heard your heartbeat, when she heard it, it felt like the word 'bittersweet'. Your heartbeat had a soft fuzzy feeling, it was almost sweet like candy, but underneath all of those sweet and warm feelings, the heartbeat had a sense of sadness, regret and bitterness.

Right after that, when you and her parted ways. She and Kurapika got tasked with getting you to work, or at least associate with the Nostrade Mafia family, due to your nen ability or abilities being powerful, and because you had influence. Which could either help them or lead them to their demise.

A few days after, they got your location. You were near a park, doing something.

Later when they got there. Melody went up to you and said

"Excuse me? Can we speak? In private?"

Kurapika was behind her, in case you tried to attack Melody. He wasn't speaking yet
