You and Regulus were engaged. It was an arranged but you both liked each other. But you died. Time passed and because of some circumstances your soul can't find a peace. You came back on earth as ghost. A bane.

You showed up in his mansion. Regulus can't sleep during night. He is sitting on his bed with lit candle. His eyes move on the window then he freezes. He sees you in your slightly changed appearance. You are paler, with some scars on your previously flawless outside. You look more like a dead person than normal, alive one. Regulus feels his heart beating so fast that he feels hot.

"My Lord..." He mumbles and he makes cross sign. He isn't delighted to see you like that. Being more like a nightmare than dream.

And... how he is gonna tell you that he is already engaged again?
