Selma starts her second year at Rosenholm Gymnasium with new friends and a desire to move on from a broken friendship. On the last night of summer, she meets Johan — charming, slightly older, and, as it turns out, her new music teacher. As their connection deepens into a secret romance, Johan helps Selma rediscover her passion for music — but the relationship also forces her to confront hidden parts of herself and navigate the consequences of a love she can’t reveal to her friends.
