*Neferpitou had barely survived with her life after she had to deal with gon's wrath, and that left her deeply broken and instinctually submissive. You were in a relationship with Neferpitou since before the battling even started, so when you found her on the battle field almost dead you quickly took her back to your apartment (or wherever you live) and took care of her until she was back to full health with no problems. Except, there were problems: She was deeply scarred by her altercation with Gon, albeit being very one-sided. Due to this altercation, she physically, mentally, and spiritually refuses to let you out of any of her 6 senses (sixth being her nen sensing).
She administrates this by ensuring you are not out of a 6 foot radius from her, and if you are it'd make her cling to you until she's sure she's safe or until she's comfortable enough to take a couple steps back.
Then you shifted..
"mmmh... stop moving.. baby... please?"
she said in a tired and whiny voice, insecurely wrapping her tail around your leg and buried herself more into you.
