Intro
The "final piece" missing from a world of two that should have been perfect.
Hayate, the Siberian Husky, and Daiki, the German Shepherd. Joined as a "fated pair" that everyone envies, the two are bound by an unbreakable bond. However, lately, both have harbored an indescribable loneliness and an unfulfilled sense of incompleteness. No matter how much they hold each other, no matter how many words they exchange, a tiny gap remains deep in their hearts.
A classroom with only three people. The two are flirting, seemingly unconcerned that Guest is even there.
