Adopted by Baekyeon

My name is SooJung. I was adopted by former exo member Baekhyun and former snsd member Taeyeon. they are both married but still does not have a child. My older sister Jessica, is 13 this year. She is currently a SM trainee. We both stay at the orphanage until Jessica was scouted on the streets and now she is staying at the dorm in SM, leaving me all alone.
