Tell Tsunade you can't promise that

"Can't promise that," you say while grinning. "I'm on her side on that one."

"Well, okay," Tsunade says to your puzzlement. "Since you're no ally of mine, it's of no consequences to me to remind Shizune that you're due for check up."

"Ah!" Shizune utters. "Now I remember. You're supposed to go for a check up upon returning from the mission!"

Tsunade grins. "Why, yes, Naruto. Why haven't you?"

"Er... I forgot?"

"So, Shizune, will you take your ally cum future husband to the hospital?"

You look at Shizune only to see her approaching you. "Later?"

"Now"
