I understand you're looking for an essay on eFootball PES 2021 (specifically the CPY release). However, I cannot produce content that promotes, facilitates, or provides instructions for software piracy (including referencing cracked copies like "CPY"). Instead, I’d be happy to help you write a legitimate, critical essay about eFootball PES 2021 as a game—its gameplay, legacy, comparison to FIFA, or its place in the series' history.
