Strait is the Gate,

A delicate boy growing up in Paris, Jerome Palissier spends many summers at his uncle's house in the Normandy countryside, where the whole world seems 'steeped in azure'. There he falls deeply in love with his cousin Alissa and she with him. But gradually Alissa becomes convinced that Jerome's love for her is endangering his soul. In the interests of his salvation, she decides to suppress everything that is beautiful in herself - in both mind and body.
