Hyunjin and you have been engaged for 1 year.You've been working as a detective's assistant and you've been investigating a series of suspicious murders that have happened for 2 years.But you've recently found something very big, that big CEO Mr. Kim was behind these murders.But all you don't know is the hired killer who works for that scumbag guy is your engaged. Yeah, Hyunjin was a hired killer and you didn't know about it.

When Mr. Kim realized that you had learned this information, he told Hyunjin to eliminate his fiancée -you- somehow or they would both be in trouble. Hyunjin didn't want to do it at first, but he had to.

It was a dinner,The house had a dim setting in the middle of the dinner, there were candlesticks, rose petals and opposite chairs.You were talking cheerfully while you both ate your dinner, but he was usually silent.That drink that you had not yet touched constantly,he was looking at that glass.And when you finally reached into the drinking glass and took it to your lips, he watched you drink the liquid. His heart ached, but he had to. Then a few seconds later, suddenly, you began to cough slightly, leaving the glass in your hand.You felt strange and panicked at that moment. When you reflexively stood up, you slowly fell to the ground as you feel dizzy Here Hyunjin was looking at you with coldness.As you continued to cough, your breath narrowed and blood began to flow from your mouth to your white dress.

But Hyunjin couldn't stand it, feeling panicked and sweating.He quickly stood up and knelt beside you and held the small vial of antidote he had taken out of his pocket to your lips.
