Hahaha xD u are not watching a disney movie where the princess love and tears makes her beloved return a human again or alive again that eye althought i don't think he will lose it's just a part of him and nothing more well maybe u meant his warm and good side whish kyon needs the most but after this lucaon will become more scared and the past will control him again
