Tsunade walked around the desk and sat directly next to Iruka, turning both of their chairs with a casually powerful grasp. In the end they were facing each other, not the desk. He tried and failed to hold her gaze. She reached out and tipped his chin up, forcing him to look at her again. Another hit landed. This time it came from Iruka's left. It felt like it must have shattered bone, ribs grinding against each other in his chest, and Iruka bit his tongue almost until it bled to keep from crying out.
“Tell me, Iruka-sensei,” Tsunade said. “How long, exactly, have you been feeling Hatake Kakashi’s emotions?"
“Are you planning to keep my hair tie?” Iruka asked suddenly, a hint of amusement in his voice.
“I’m holding it prisoner for crimes against the citizens of Konoha.”
“What are the charges?”
Kakashi smiled, twirling the band around his forefinger like a kunai. “Perjury and willful concealment.”
Iruka huffed and shook his head, lips thinning in a way that made Kakashi think he was holding back a grin. “You know, if I’d realized you had such a thing for long hair, I would have started wearing mine down years ago.”
Kakashi’s thumb caught the hair band, halting its revolution.
“Years?”
(Or, in which Iruka asks for a single night, and gets a whole lot more.)
Kakashi had never thought of himself as a baby person, but apparently he'd become one while he wasn't paying attention. Luckily for Kakashi, Iruka was the best parent-partner person a shinobi could ever ask for.
