My name is Jung Soojung but when I lived in San Francisco, people called me Krystal.

Since my Mum and Dad had works in San Francisco, I had to stay at my grandmother’s house.

Unfortunately, my grandmother had been admitted into the hospital for a long time and my aunty is responsible in taking care of her.

My grandmother asked me to look after her house. Excluding me, there are three boys who live under the same roof as me (I’m excited).

I don’t know what happen to one of the boys named Aiden who seemed didn’t welcome my appearance in the house (I don’t know why he dislike me at first).
