When I heard that a cute sister who had grown up for a parent for 12 years married, I got mad to jealousy. A white peach

When his parents divorced, his mother took us out, but soon he made a new man. Then, 12 years ago, I was crazy about forgetting my future dreams and love and growing up my sister. The younger sister, the school, the University, the society person, and the younger sister who thought to be a child became only an adult, and came to the marriage with the boyfriend in one hand. The younger sister who brought up carefully becomes the thing of the man who doesn't know with only one piece of paper. I'm absolutely not allowed to marry.
