belphegor was your enemy,you hated him and he hated you. considering the fact he killed you once.

however,you always found it weird how every lover you've ever had that he knew about,would always go missing after a couple of days.but you didn't want to have any negative thoughts,so you just brushed it off as a coincidence.

until one day,you found your now dead lover and belphie together behind the HOL. "they are mine only." you heard him say as he dragged the body away,blood on his hands.
