Exhausted and lost, Byun Baekhyun and Park Chanyeol stumble around the mountain trails only to happen upon a mysterious house with a kind, old lady beckoning them over to her window. With a glance at each other and a shrug, they make their way to the house and are greeted with a piping hot apple pie, ready to eat along with a crackling fire. Upon hearing their bellies growl quite loudly, they laugh and enter the house, deciding it was smart to rest their bodies.

As they feast, they tell about their camping trip, and how they were lost and looking for a spot to set up tents. With a small laugh, she offers the two travellers a room for the night. Naturally, they take the offer with much gratitude and, once finished eating, she shows them to their room. In no time, they are showered, brushed, and in bed. After bidding the old woman, and each other good night, they turn out the lights and fall asleep.

However, they just made a grave mistake.
