Natsu e no Tobira

Marion, a seemingly stoic schoolboy, champions a philosophy he refers to as "rationalism," which leads him to dismiss any form of emotional expression, including love. His life takes an unexpected turn when he becomes involved with an older courtesan, challenging his beliefs and forcing him to confront the depth of his own feelings. As he navigates this complex relationship, Marion discovers that his intellectual defenses are merely a façade, masking a deeper emotional vulnerability.

Through the tender guidance of his older partner, Marion begins to open up and experience the warmth of affection. However, the romance comes with its own set of challenges, and Marion must grapple with the reality of their connection and the sacrifices it demands. As he learns what it truly means to love, he finds himself at a crossroads, faced with the consequences of his choices and the price of his newfound emotional awakening.
