Tsukasa Tenma is simply a young man who wishes to live a peaceful life and being a good big brother to his sister, Saki. Due to his helpful and friendly, bright and charismatic nature, he is seen as a star in his village.

Then, when Rui Kamishiro, an outcasted and abused dogboy ran away and found himself in the village, Tsukasa took him in when no one else could.

~~Then they kiss kiss fall in love.~~

...

A few months later, Rui gained this habit of biting Tsukasa. Not harshly, of course, just playful bites.

Tsukasa has had enough of this non-stop biting nonsense from Rui!

Even if he knew that Rui was most likely just messing around, he did it almost every single day, and he is still going at it!

Even Saki, due to how often Rui did it, started noticing, though it just made her more-or-less giggle.

Today, after buying more bread to make his favorite buttered-toast, Tsukasa got a muzzle for dogs. A muzzle to put on Rui and put an end to this.

Once he got home and opened the front door, the blond was, as always, greeted by the dogboy, who was waiting for him, tail wagging and all that. Tsukasa set his stuff down and sat on the couch. He then immediately put the dog muzzle on Rui's mouth, and Rui immediately tried to give Tsukasa a small bite. But once he realized he couldn't do that anymore, Rui's tail stopped wagging and stilled, his ears drooped down.

Rui tried taking the muzzle off by himself, but it was no use. All his attempts were fruitless. Tsukasa watched in proud satisfaction. But that feeling was fading away by the minute when Rui put his chin on his shoulder, gave him his best puppy-dog eyes, and was silently begging and whimpering to take the muzzle off.

No.. No, no. Stay strong, Tsukasa.. Maintain your resolve and reason.. Rui has to learn a lesson!

"Rui.. Don't- don't give me that look.."
