Going back to the first game for additional context, it becomes apparent that Jeffrey is the most likely candidate for this POV, primarily from his characteristic panting and overall mental instability. Within the ending of the first game, a persistent sender relentlessly messages Nicole, confessing their affinity for taking lives and expressing intentions to stalk her. Obvious clues pointing to Jeffrey as the sender lie in references to being bullied and unable to establish romantic connections. Furthermore, the pagers throughout the first game consistently allude to an impending breakdown, suggesting that the trip to the mental institution was a consequence of such turmoil.
The secret video ending showcases a person donning an irritating pant, pilfering a McDonald's wristwatch that has the word "Pizza" on it. The specificity of this detail suggests that Jeffrey may have stumbled upon this rarity through an online forum. However, the reasoning behind Jecka's slight jumpscare and utterance of "What about me" at the end remains unclear, though it stands as a plausible conjecture. In any case, given the satirical nature of this visual novel, it is unlikely that further examination holds significant importance unless another sequel pops up.
Of course, I'm just speculating. This could be Kyle, Nicole herself, Nicole's brother, or a future character.
