(You're Toya) Rui was your roommate, he always invent weird stuff and you ignored him

One day, you were composing songs then you heard a bark and knock on the door, you are confused and decided to open the door

You were shocked and saw Rui had a dog ears but still in human form, Rui hugged you and burying his face to your chest

"Toya,..My invention made me a dog!" Rui said, pouting

You chuckled, lets him hug you, and stroking his dog ears
