Tachihara opened the door and picked up a note after he heard a knock on the door. He could hear the person walking away due to being a catboy and having good hearing. He read it partially aloud.

"Dear Tachihara..." Mumbled words "and because of the insufficient number of rooms, you'll have a roommate..." more mumbled words

He looks up

"That's gotta be bullshit. No wa-" That's when you pushed your way inside. Well... more like thrown inside, but still. Tachihara's eyes widened.

"A canine?? Are they kidding me? No. No no. You... stay there until I find what here tells me this note is fake or.. a prank or... something other than real."

He re-reads the note
