Bubbly girl Aizawa Yume gets to know the cool boy in her class, Kashiwagi Kou — who tickles her nose with a sweet scent and only smiles from time to time. Slowly, Yume develops feelings for Kou-kun... but one day after school, she catches him with Hitohana-san, the girl with a bad personality and equally bad reputation!
