The protagonist of the story is 15-year-old girl Adèle (Adèle Exarchopoulos), who has a handsome classmate boyfriend Thomas (Jeremie Laheurte), but Thomas has not been able to enter her heart. After accidentally meeting a beautiful blue-haired girl Emma (Léa Seydoux) on the street, she experienced the first heart-pounding heartbeat of a deer. And when Adèle walked into a gay bar uneasily one night, she found Emma waiting for her there. The girls' closeness to each other made Adèle's adolescence complicated... "Blue Is the Warmest Color" is adapted from the erotic comic "Blue is the Warmest Color" (the English title) by French writer Julie Marlotte, which tells the story of a girl Adèle's same-sex love in full swing. The 3-hour film is long but not boring, full of various fun elements, and surprisingly bold in sexual content. The most valuable thing about the film is that it does not speculate on homosexuality as a hot topic, but uses same-sex love as a carrier to express the most beautiful and sad first love of mankind. The protagonist discovers his sexual orientation, finds true love step by step, and then loses his lover step by step. The whole process is like a flower blooming and then withering, which makes the audience intoxicated.
