REALLY I LIKE YOU (1978)

Ji-yeong has a biking accident and is aided by a boy who is practicing to become an Olympic marathon runner. The young man falls ill during a practice and is forced to give up his dream due to a previously undiagnosed heart disease. Ji-yeong wants to help him, but her parents don't allow it, so she steals a camera to pawn for the money for the boy's hospital bill.
