Blue Flag Vol. 1
For some reason, Taichi Ichinose just can't stand Futaba Kuze. But at the start of his third year in high school, he finds himself in the same homeroom as her, along with his childhood friend Toma Mita, a star athlete. But one day, Futaba opens up to Taichi and admits she has a crush on Toma. She then asks for his help in confessing to him! There's just one problem-Toma seems to already have a secret crush on someone else.
