The Fragrant Flower Blooms With Dignity(2021)

This story takes place in a particular town with two infamous schools in constant dispute: Chidori High, a boys' school predominantly attended by low-class students with damning grades, and its neighbor Kikyo Girls' High, with most of its female students coming from wealthy and prestigious families. One day, high school second-year Rintaro Tsumugi, a fierce-looking but gentle-minded student at Chidori, is helping at his family's patisserie when he encounters a female customer by the name of Kaoruko Waguri. Rintaro enjoys his time with Kaoruko, as she doesn't judge him for his appearance, but this blissful peace is quickly disturbed when Rintaro makes the discovery that Kaoruko is actually a student at Kikyo. This revelation marks the beginning of the two's strenuous tale, as they fight against the limitations placed upon them by their schools and surroundings in an attempt to find their own path!
