In a picturesque Japanese town, the heat of summer is felt both in the atmosphere and in the hearts of its inhabitants. The story revolves around a young artist who struggles to find inspiration and purpose amidst the monotony of her daily life. She feels that her life lacks excitement until, during one of her walks along the riverbank, she stumbles upon a group of young people organizing a fireworks festival. Intrigued by the energy and joy they emanate, she joins them and discovers a vibrant world where creativity and friendship flourish.
As she becomes involved in the preparations, she forms a special connection with a boy from the group, whose adventurous spirit awakens something dormant within her. Together, they embark on a series of mischiefs and adventures that not only revitalize her passion for art but also teach them about the importance of living in the moment and daring to dream beyond the ordinary. However, the festival and the love they have found are not enough to escape their responsibilities and the pressure of an uncertain future.
This poignant ode to youth and freedom culminates in an explosion of colors in the sky, but also with the harsh reality that sometimes the most beautiful moments are fleeting. The story invites reflection on how, despite the inevitability of change, there will always be room for beauty and creativity in our lives.
