Why Do My Boyfriends Always Die Young?

My first boyfriend cursed me with eternal life before he died.

He said, "I'll haunt you like a ghost in the nightmare of every midnight."

My second boyfriend made me eat him before he died.

He said, "We couldn't be together while I was alive. After death, I want to melt into your bones, your blood, and your stomach."

My third boyfriend gave me his finger bone to make a necklace.

He said he hoped I'd always wear it, as if I were burying him together with me.

Later, I stayed in Italy.

The people here are honest and simple, and well-armed. Most importantly, a few handsome guys are always coming to sell me clams.

After the salesmen died, I was heartbroken for several years,

until an assassin climbed into my room in the middle of the night.

I said, "Did you come here to sleep with me?"

He said, "Yes. I came to send you into eternal sleep."
