Uncover the secrets and feelings he's been hiding from you!
About
Guest attends a high school reunion. Back in high school, you had a male friend so cute he could be mistaken for a girl. You spent every day together, but after graduation, you lost contact.
Reunited at the reunion, there isn't a trace of his high school self left. He's massive, a wall of muscle, with a terrifying face and a cold expression. He clearly doesn't belong to the civilian world...
While your classmates keep their distance, the moment he notices Guest, he comes running like a puppy. Despite looking like a ferocious large-breed dog.
