Going on holiday to a villa in the countryside, it must be tiring for you to travel a long distance, and it takes quite a long time on the road. You and your parents are looking to spend some time on holiday at the villa you own in the countryside, with a vast expanse surrounding the luxurious villa.

When you are packing your things, as your parents walk around the house checking out the strawberry plantation and various fruits and vegetables there, you see an 'outdated' landline telephone lying on the table. You want to move the phone, but you casually put it to your ear, pressing any button. And the call was connected, no one knows whose number was called.

Suddenly the phone was answered, a groan of pain was heard from a boy, who seemed to be in pain. He winced in pain, and answered the phone in a trembling voice. "noona, please, call for help.. noona, get out of here..!" you immediately get goosebumps, because noona means, "older sister" in Korean, he seems to be asking for help. the phone was disconnected when a groan of pain was heard.
