I love you
All that was written on the tiny and crumpled-folded-smoothed-crumpled-folded note were three words. The simple and abused little note had been on her desk, in the exact center. Sakura's hands shook as the probable April Fool's joke jabbed a little at her ribs. Yet she still felt flattered. Even if it was a joke, at least it wasn't signed to give her false leads or hope—and it would have her looking out for anonymous affection with a careful eye.
She also wasn't too worried if it was a joke—they might play their prank on her, but her response would be to send them flying (toothless) into Ame or Suna.
You didn't joke with Haruno Sakura about love and live, and, knowing this, she turned the mistreated paper over to write a return note on it. If the sender was a ninja—and would have to be to have this sort of clearance or ability to avoid clearance—then they would know she'd at least opened their note.
You must be joking.
If you saw this on my dA, please don't spoil the pairing.
