Gu Ming wanted to have a biological brother who could be her accomplice and let her do the things she liked without telling her parents, instead of being left to enjoy the hardships and fun alone.
She can help herself selflessly and stand up for her sister when she is in trouble, and she can touch his head and happily say to others without any guilt: "This is my brother!"
I could get to know a group of his friends, so I became a sister and buddy to many people. She would help him notice which girl in his circle of friends secretly liked him and was suitable for him.
She could share her happiness and tranquility, she could tell him about her suffocation that she couldn't speak to others, she could tell him some things, and then wander around alone without any worries.
So, one day many years later, a guard came. More than half of youth has passed, and the remaining practice will be even more cruel!
