Jun is a girl who cannot speak due to a magical seal placed on her words. Her muteness stems from a past incident in which something she said as a child caused her family to fall apart. An egg fairy then intervened by silencing her to prevent further damage. Since then, Jun has tried to avoid attention and live a quiet life. Unexpectedly, she is chosen as an executive member of a community outreach council and assigned to take the leading role in their musical production.
