Her parents died and she came to his home at the age of seven.
Good Samaritans adopted her.
Everyone said she was his little wife, but he just smiled and said nothing.
When she was wronged, she would always look up at the person who was two years older than her and a head taller and say: "They bully me. I am your little wife, you have to support me."
When she grew up, she never thought she would be with him. She thought he just regarded her as an older brother.
Intention: The other half in the future may be the big brother who leads the family, or it may be the person who has played with me since childhood.
