Yûbue (1967)

There is a high school student whose family went broke. They lose their house. The student stands in front of his former house. He stares at the flowers in the garden and sees a schoolgirl who lives in his former home now. He asks whether he can have a particular flower. The boy wishes to attend Tokyo University and the last memory of high school is a trip with his friends, but he has little money to bring along and spend. An alternative is to sleep on the beach where he coincidentally meets the same girl again. They fall for one another, but she is engaged. They make plans.
