Natsu E No Tobira

Marion is a young schoolboy who prides himself on his adherence to a philosophy he calls “realism”. Because of his distain for emotional display, he ignores anything remotely akin to affection. But when Marion is entangled in a romantic affair with an older courtesan, his rationalism is revealed to be little more than a cover for his own emotional immaturity. Learning to love, Marion blossoms under his older lover’s care but unfortunately, Marion has yet to learn the true price of the affair.
Classic 1976 shoujo by the author of “Kaze to Ki no Uta” and one of the first shoujo titles to include shounen ai elements.
