"I love you, Duoduo."
"You're disgusting, Chen Jing."
When Chen Jing was six years old,
his parents returned after being away for half a year, bringing home a one-year-old child.
They told him,
"She's a friend's child. She's going to stay with us for a while."
They warned Chen Jing that she was his little sister from then on.
He had to treat her like his own sister.
Chen Jing didn't care. It made no difference to him whether she was his parents' biological child.
He loved his little sister.
At last, he had someone to keep him company.
He thought Duoduo must like him, too.
Later, his parents left again, leaving him and his little sister to live together.
He was even happier.
Now his little sister would belong to him alone.
He would never be alone again.
As they grew older, he realized that there was something wrong with his feelings.
But he soon accepted them without hesitation.
He loved Chen Duo.
No matter what it took, he would never give up.
