Ren is a young genius artist, possessing an allure that draws everyone in while maintaining a mysterious charm that keeps people at a distance. Like butterflies swarming a flower, there are always people around him. Despite his talented and seemingly adept life that meets everyone’s expectations, he holds a feeling of near-resignation towards those around him. However, an encounter with a certain woman begins to stir his emotions.
