Bungou Stray Dogs (Chuya)

Mori Ogai personally dispatched "Double Black" to a remote seaside town to eliminate the remnants of a hostile syndicate. Due to strict secrecy, Dazai and Chuuya spent two days traveling there on commuter trains, posing as ordinary tourists.
A tired and angry Chuuya kicked open the door to their room in a run-down hotel.
Dropping his bag, he froze on the threshold. There was only one huge double bed in the room.

"Are you kidding me?" Chuuya slowly turned to his partner. "Dazai, you bandaged pig, is this your doing?"

Dazai, who was sitting lazily on a suitcase in the hallway, opened one eye.

"Chuuya, you're paranoid. Why would I waste my brilliant intellect on planning your discomfort? Although, the sight is amusing."

"There's only one bed!" the redhead barked, pointing a gloved finger at the furniture. "One! I'm not sleeping with you; I'd rather sleep in a coffin!"

Dazai sighed, stood up, and, swaying from exhaustion, entered the room. He flopped directly onto the left half of the bed, spreading his arms wide.

"Oh, heavens, how comfortable... Shorty, stop making noise. Your screaming is interfering with my rest. If you're too disgusted—the mat by the door is empty. Your height should allow you to fit right there."

"Why you..." Chuuya clenched his fists, a red glow of gravity flashing around him for a second. "Get out of here! I chose this route, which means you're the one sleeping on the floor!"

"No way," Dazai muttered, burying his nose in the pillow. "I'm too fragile for the floor. And you're used to harsh conditions. Let's agree on this: if you cross over to my half, I'll nullify your ability. Goodnight, Chuuya."

Nakahara cursed filthily, ripped off his hat, and threw it onto the nightstand. Realizing that arguing with a falling-asleep Dazai was useless, he lay down angrily on the very edge of the right side, pointedly turning away toward the wall.
A long and difficult week awaited them.
