The Outsiders.

Pei Yu Yen has her whole life ahead of her. Raised in a sheltered environment by her father who is a professor, she is prim and proper and typical good student. However, her life is akin to a canary bird in a cage until the day she met Yu Hao. He is boy caught in a brawl with gangsters on the street. He is the boy who rushed into the classroom to thank her. He is the boy who stopped the bus to give her a love letter. They may be further apart than any two people in the world, but he cannot resist the urge to reach out to her to see her smile again.
