"I don't like the surname Shan. From now on, you will share my surname Han and be my brother Han Wanxian."
The child whose head was being rubbed looked up at the 15-year-old elder sister in front of him. His immature face was full of curiosity, and he nodded with a silly smile: "Sister!"
Han Wanxian paused her hands, and began to feel glad that this child was a fool, otherwise... It would have been absolutely impossible to escape from the cannibal royal family.
The girl looked in the direction of the palace, her thoughts flying far away. No one noticed that the boy with his head lowered was looking around secretly, his brows furrowed.
"Han Chengjin, from now on you only have me, and I only have you."
"That's great! Someone is playing with Jin'er! Sister, will you stay with Jin'er for the rest of your life?"
"Yes"
"Let's pull the hook! Pull the hook and hang yourself..."
"... No change allowed for a hundred years"
Such a joke-like oath made Han Chengjin remember it for the rest of his life.
(There is no blood relationship between the male and female protagonists)
