All Atsu has ever wanted is a dog of his own... and all Junya has ever wanted is Atsu! After being friends since childhood, dog-like Junya and cat-like Atsu now attend college together. One day, Junya finally drops a bomb: he's in love with Atsu and wants to have a sexual relationship with him! Even though Atsu agrees, he doesn't tell Junya if his feelings are returned. Aren't they both supposed to be in love? What's more, aren't dogs and cats supposed to be natural enemies? With lots of training, perhaps Atsu will come to learn that having Junya is even better than having his own pet!

University students Junya and Atsu have been friends since they were kids. But when Junya tells Atsu, "I want to get with you so bad," their whole relationship changes in a flash! But Atsu is at a loss as to how to turn Junya's tendency to monopolize everything towards himself. In the space between friendship and love, which way will the pendulum of burgeoning affection swing?
