He first met her when he was eight years old.
In the corridor of the hospital, he was wearing hospital clothes, and she was hiding in the corner crying.
That year, she was six years old.
The first time he stopped trying to bully her was on a rainy day when he was seven years old.
She held up an umbrella for him and stood in front of him like an angel.
That year, she was the same age as him.
