The Les Mis fanon interpretation of Jean “Jehan” Prouvaire is horribly mistaken and the reason is as simple as knowing the difference between ‘romantic’ and ‘Romantic’.
“In the context of romantic love relationships, romance usually implies an expression of one’s strong romantic love, or one’s deep and strong emotional desires to connect with another person intimately or romantically.”
Commonly, Jehan is portrayed as romantic. He is a free-spirited poet who writes verses of love and wears a crown of flowers on his head, which is fine for you to do, but you miss his characterization entirely by depicting him as a happy ball of sunshine 24/7.
Let us take a look at the definition for Romantic (note: capital R).
“…it was also a revolt against aristocratic social and political norms of the Age of Enlightenment and a reaction against the scientific rationalization of nature. […] The movement validated strong emotion as an authentic source of aesthetic experience, placing new emphasis on such emotions as apprehension, horror and terror, and awe—especially that which is experienced in confronting the sublimity of untamed nature and its picturesque qualities, both new aesthetic categories.”
