Kanojo wa Sore wo Gaman Dekinai

A high school student named Kusahana Ryouta consistently wears a full-body dog suit and refuses to remove it. His routine remains unchanged until he drops the bag of a girl he admires, causing her sports pants to fall out. As he picks them up, he briefly considers their scent when he is caught by his new homeroom teacher, Kizawa Ayame, also known as Ayane-Chan. To prevent her from revealing the incident, he offers to do whatever she demands. She accepts and requests that he allow her to sniff his body in return.
