Our Bittersweet Jam Chapter9

Mizuno Sawa, high school first-year, is a quiet and reserved girl living under the social radar. Her school is also home to the band "Blue-Burst", made up of four boys from the pop music club and hugely popular among the students. Of course, Sawa and the band members pass their time at school without ever crossing paths - except, Kouichi from the band is secretly her twin brother! Kouichi is an amateur model on top of singing in the band, and basically the school's superstar; but despite his superstar smile on the surface, his true face is a sneering demon. When he double books a modeling gig with make-up lessons at school, the idea strikes him to make Sawa take his place at the lessons. Poor Sawa has a complex about defying her brother, so in the end she puts on his boys' uniform and heads to school. From that day her plain, quiet high school life changes completely! It's a melody of love and thrills in this coming-of-age story!
