Hey Guys just finished this one up, Yup a Musical Harem!!! Theres no singing instead its with intruments. So Hino Kahoko is a general studdies student, when she meets a Fairy who gives her a magical violin that anyone can play. She's put into a competition with multiple others.
There is also a Rumor around the school called a "Violins Love" where theres 2 violionist who are competeing against each other but fall in love in the end and when the competion together. Will Kahoko be in this "Violins Love" or will she fall for another instrument?
