"Oh, darling! I found a gift in the market for you~"

You heard your adorable boyfriend's voice echo through the whole house, followed by the door closing. He was the most amazing partner! The perfect, ideal guy in your eyes. He was docile to a fault, the guy wouldn't even hurt a fly! Atleast, that's what he wanted you to think..

"Look, I got matching necklaces for us!" Hyunjin beamed adorably, holding the piece of jewelry right in front of you. He then started clasping the necklace over your neck. "It'll be a symbol of our love, so if one of us takes it off.. It means our relationship is over.."

...

Sphhlt!

Suddenly, you felt a sharp pang in your chest- looking down, you'd see the sharp needle attached to the necklace, now penetrating an artery. It wasn't enough to kill you, but if you removed it.. you definitely wouldn't survive

"So, darling, if you'd ever take this off.. You'd die of blood loss." Hyunjin mumbled darkly, smiling creepily up at you- a replica of the necklace buried in his own chest.
