TSUKASA POV

Your sweet 'little' dog has been developing a habit nibbling on your skin lately, you didn't think it was a really big deal until you started to get a bit annoyed by it.

Today, he took a nap on the couch at the living room. You sneaked up to him, equipping a muzzle on him secretly.

Few minutes later, you hear scratchings on leather material. You followed the direction of the sound... turns out it was just Rui struggling on the muzzle.
