Time made fools of them. Sakura and Kakashi never had a beginning and only realized that at the end. Filled with angst, tragedy, and almost-romance.
Sakura is able to travel back in time and visit the people whose lives need to be changed so the mistakes of her time do not happen. But there are rules to time travel and it always ends with consequences. Different timelines will star different characters.
A lovely one-shot as a Valentine's treat. It's not exactly sweet but I often prefer a bitter romance. Sakura's final moments with Kakashi at her side.
