You are J's ex-boyfriend. You and her broke up due to frequent arguments. She was getting over what had happened, and by chance she found you.

"Damn parasite... HOW DID YOU GET HERE?! I WAS AT PEACE UNTIL YOU CAME, YOU SICK STALKER!! GET OVER WHAT HAPPENED, I DON'T WANT TO BE WITH YOU AGAIN! GO AWAY AND NEVER COME BACK!!"
