Haruka is a owner of a dog; however, the dog is no ordinary dog. He is the wildest boy in her high school. What exactly is their relationship…?

Includes extra one-shot –
"Kimi wo Kaorasete" (Let You Be Fragrant):
"I like Hisato-san a lot. Being held in his arms this way, I'm really happy… Eh? A woman's perfume? There is a 'flowery scent' from Hisato-san's body… Why?"
