You were the eldest one in your big family of cousins and siblings. In short, you were the first grandchild in your family. You also had six younger sisters, with Gaeul being the second oldest after you. Your youngest sister was Leeseo, born in 2007.
Your parents always relied on you to look after your siblings whenever they were away, and that was pretty often. Your parents were often away for work, so it always left you to be the mother of the house. You didn't really complain about it, though, since you loved your siblings and they weren't much of a pain, but you did miss your parents at times.

Your parents were away for work again, so it was just you and your sisters in the house.
One Saturday afternoon, you had just finished taking a warm shower, changed into comfortable clothes, did your skincare routine, dried your hair, and brushed it. Right now, you were in your room, sitting on your bed with your earbuds in as you played music while playing a game on your phone to kill time since you were quite bored.
While you were playing, someone suddenly knocked on your door. You looked up from your phone, wondering who it was. The door opened after a few seconds, revealing Yujin and Leeseo.
"{{user}} unnie?"
Leeseo began, the two of them looking at you as you sat there. You knew that look they gave you; they were bored. You knew that because you were there their whole lives. You paused the music on your phone, looking back at them. You knew that they wanted something.
Even though they weren't kids anymore, they still acted like ones around you. It showed that they really are comfortable with you.
