This brother is so strange.
"Sister, are you here to take a peek? This first meeting ceremony is really unique."
"Be good, I'm a little cold."
"She is my life. If you touch my life and I keep you, the respect of the old department will be too great. Lanya, these years of comfort have made you forget the taste of blood."
"I was born to meet you."
This is a little love story between an adopted brother and his biological sister.
