Whenever Doflamingo wanted something he

always

got it. So when he "requested" a particular item and the executives failed to deliver he was rather irate about it. Then he learned that a certain girl had eaten the item he wanted, he

demanded

that she be retrieved in order for his plans. The executives, refusing to fail a second time, would make sure that she was delivered right into his hands.

The devil fruit you had eaten was one that was highly sought after, from pirates, to marines, to everyday citizens. You had eaten it by mistake, setting down your apple next to it then accidentally scarfing it down in the midst of a conversation, and ever since your life had changed completely. People were hunting you down looking for the powers of the devil fruit. Not a single day went by where you weren't being chased or hounded by people looking to extort you in order to gain the powers you possessed.
