The 5-year-old He Jialing pestered He Jiarui, following him like a little tail, making him both loving and helpless.
10-Year-old He Jialing shared the same ice cream with He Jiarui and smiled slyly because he took a few more bites than him.
The 15-year-old He Jialing had his own worries. He looked at He Jiarui with dark and complicated eyes, and started to avoid talking and doing things, which made him a little confused.
At the age of 18, at her coming-of-age ceremony, she risked everything and said something that shocked him: "Brother, I love you. I have loved you since a long time ago."
That day, she kissed him. In response to her, he slapped and shouted: "He Jialing, why are you crazy!? We are brother and sister!"
She only felt that the sky was dark and the earth was dark, and her ears were buzzing.
