The romantic version of the friendship between Narcissus and Goldmund in Hesse's book, my favorite, recently read for the 4th time. From the inside cover:

NARCISSUS

an ascetic monk; a rigorous intellectual remains in the monastery to become an abbot; the epitome of the masculine, analytical mind.

GOLDMUND

romantic, dreamy, flaxen-haired boy; celebrates the lush, lyrical, rapturous, sensuous quality of women; leaves the monastery to find his true nature; he epitomizes the feminine mind.

NARCISSUS AND GOLDMUND

two antithetical natures, the best of friends, who under- stand and assist each other.

"Hesse lifts the contrapuntal play of conflicting forces into a plane as close to music as words will come. What lingers in the reader's mind is a melancholy melody, a romantic "lied" full of wanderlust for a trip into the id." -Saturday Review

I recently discussed the book and others here. https://thetaoist.online/hermann-hesse-alan-arkin-and-marcus-meet-in-a-bar-to-discuss-philosophy-with-marcus-7582ce0bad14 I don't think you've read this one.
