"W-What are you sniffing at!" Nio Katsutoshi, protagonist and judo club affiliate, was having a bit of a freakout out the train. That's because Shimizu Rinka, the student president whom everyone adored, was smelling him. On the best of days Katsutoshi had a complex about his body odor. It wafted to any distance, and it was embarrassing. His cheeks burned with shame. But, looking at Rinka, he saw her face was blushing even redder. His scent was a trigger that seemed to be making her aroused! What's more, it had wafted into the nostrils of Kumakura Isuzu, his childhood friend...... This is the story - your story - of Nio Katsutoshi, the object of affection of kun-kun scent fetish heroines. [Edited from DLsite English]
