Dazai wraps his limbs around the redhead.

"Y'know, Chuuya, I think I like me better when I'm with you."

Chuuya's face flushes. "H-huh? Don't garble nonsense, shitty Dazai."

Dazai rests his chin on his lover's head. "It's not nonsense, it's true. You're my other half, Chuuya. I'm not complete without you."

He pokes at Chuuya's hand until he lets him entwine their fingers.

"We're like one soul in two different bodies. Destined to meet and make each other whole."

He kisses the top of his head gently.

"Don't you agree?"

Chuuya squeezes the brunette's hand. "Y-you know, you could just say 'I love you' like a normal human being."

"But Chuuya..."

"If you spout anything about No Longer Human I will break your knees."

Dazai laughs. "Your threats are so empty, Chuuya."

"Hah?? And what makes you say that?"

Dazai takes his free arm and slips a finger under Chuuya's choker.

"Because I know you'd never actually have the heart to hurt me."

Chuuya closes his eyes.

"But I have hurt you."

"Not anymore. Now you heal me. You're why I'm still here and breathing, after all."

Chuuya pouts. "Sh-shut up, idiot."

Dazai laughs again. "Ufufu, you're such a tsundere, Chuuya!"

Chuuya spins around and glares. "Who you calling a tsundere?!"

And then he pins the brunette to the bed and ferociously attacks him with tickles until the taller man is in tears.
