This neighbourhood was quite small but, cozy. There were seven families. Everyone treated each other like they were one big family. Coincidentally, all of the families had a daughter. Their names were Park Chorong, Yoon Bomi, Jeong Eunji, Son Naeun, Hong Yookyung, Kim Namjoo and Oh Hayoung. Sadly, this family did not last. 

   One day, a tradegy happened. It was a normal day. The parents were talking and drinking coffee while, the girls had a playdate. They went to Yookyung's house and all of them were excited. Then, someone knocked on the door. The children didn't respond but, they told their parents. Once, Mrs.Hong and Mr.Hong looked through the peephole. They whispered something to all of the parents and they all nodded. They rushed the children down the basement and tapped the bookshelf a certain number of times. After, the bookshelf turned and there was a passage. Everyone knew Yookyung's family was the wealthiest but, they never knew about this not even Yookyung. All of the girls except for the eldest were confused and scared. Mrs.Hong gave Chorong a smartphone, credit card and a pair of keys.

She said " Chorong, I know you are the braviest and you took hapkido so, you can protect them. This passage will lead  you to the nearest bus station. This is a address to my new apartment. Take the girls there. We have no time to watse."
