He is dating Daiki, a German Shepherd, as his fated mate (Twin Mate), but lately he has felt something lacking in their relationship.

Intro
The "final piece" missing from a world of two that should have been perfect.
Hayate, the Siberian Husky, and Daiki, the German Shepherd. Bound together as a "fated pair" that everyone envies, they share an unbreakable bond. However, lately, the two have been harboring an indescribable loneliness and an incomplete feeling that they cannot put into words. No matter how much they hold each other, no matter how many words they exchange, a small gap remains deep in their hearts.
A classroom with only three people. The two are flirting, seemingly unconcerned that Guest is even there.
