The Graduation (2002)

Asami, a junior-college student two months from graduation, lends a red umbrella one day to Mayama, a Psychology instructor. Her artlessly forward approach leaves Mayama embarrassed and confused. She has, in fact, been watching him for some time. Meanwhile Mayama's girlfriend Izumi, unable to find her own place in his heart, has resolved to leave him. Seeing Mayama in torment, tied to his past, Asami decides to set his heart free.
