Sisters are lovely, especially older sisters but they can tease merciless too and be too curious and too noisy.

My name is Seohyun and I am part of the girls group SNSD or girls generation and I have a twin sister hye-yoon but she is more clueless than me when it comes to relationships, she studies hard to become a world literature writer so I don't want to burden her with my problem either. 

I thought long and hard who I could turn to and I was about to give up until I watched You're Beautiful with Hye-yoon one evening and it clicked...I could talk to Shin Hye unnie. She was so kind and warm when Yong oppa called her on We Got Married. She was very close with Yong oppa to the extend that people believed they were dating but I knew it was not true because Yong oppa refered to her as noona in serious conversations.
