A Picture to Remember

She never wore a helmet because she liked the feeling of the wind in her long hair. But her father didn't know that.

I read A Picture to Remember. The main character like riding motorbike without her helmet. One day, she caught a traffic accident. And she lost her own memory. She met a man during the accident. She and he felt in love. I thought that I couldn't understand her feeling. Why did she like riding without her helmet. She must be catch an accident. Also her family should have been angry to her. There are many things which I can't understand.
