The Melancholic Princess, widely known by the name Sonee, is a popular reaction image and aesthetic meme featuring a blue-toned, sorrowful anime character. Originating from digital art circles, the image resonated with internet users due to its hauntingly beautiful depiction of sadness and existential dread. It is frequently used to represent 'main character syndrome' during moments of minor inconvenience or deep reflection. The meme gained significant traction on platforms like X and Pinterest, where users pair the princess's dramatic expression with captions about burnout, unrequited feelings, or the crushing weight of modern life.
