“I will kill you. But you must keep your promise…”

It was Han Seo-Kwon, the stalker who had been following Kim Yu-Young, who saved her from being nearly raped by her fiancé. This time, he promises to kill Yu-Young’s father for her sake, who is suffering from violence.

“From now on, you must not die without my permission.”

The price of the promise was not to die without his permission. But…

“Why didn’t you keep your promise?”
“How can I… not… die…”
“There is no such way.”

Yu-Young, who had lived her life with freeing her mother as her sole goal, no longer had the will to live.

“You must not die.”

But why is this man telling her not to die, even to this extent?
