Marion is a young schoolboy who takes pride in his commitment to a philosophy he terms "realism". Due to his contempt for emotional expression, he disregards anything resembling affection. However, when Marion becomes involved in a romantic relationship with an older courtesan, his rationalism proves to be little more than a facade for his own emotional immaturity. As he learns to love, Marion flourishes under the care of his older lover, but unfortunately, he has yet to understand the true cost of the affair.
