"Yuuko-san!" A tall, lanky teenage boy with black hair and glasses called out. He was wearing an apron and running around the shop with a duster. This boy was a part timer in the shop; he worked day and night in order to pay off his debt. He owed the store owner a lot. But what he owed her wasn't cash, no, it was much worse. She demanded his blood, sweat and tears.

"WHAT?! Stop yelling so loudly so early in the morning!" A tall woman with very long black hair and red eyes groggily complained as she sat up.

"It's already 11 o'clock."

"WHAT DO YOU MEAN ALREADY?! Lemme sleep!" She screamed as she threw her hands in the air and then fell back down onto the couch. The tall boy waved the duster before her face and a cloud of dust formed. "AHCHOO!" Yuuko sneezed and started to cough uncontrollably. "What! What do you want!?"

"Where did that book on the coffee table go?"

"Oh a customer came and I gave it to her."

"Then where did the key go?"

"Obviously, I gave it her". She replied with a "matter-of-fact" tone.

"I thought you said that the book should never be opened?" The boy questioned curiously.

"Yeah."

"What? Then why did you give her the key?"

"Simply, because she asked."

"So, you gave it to her because she wouldn't open it?"

"Who knows", Yuuko-san replied. Then, her expression suddenly changed in to a serious and frightening tone, "but either way, that book was never meant to be opened."
