I don't own Naruto, if I did ShisuIta would be a canon + SakuHina would kiss at least once.
Sakura and Hinata were best friends since they can remember. They supported each other in love, training and whenever the other one needed help after mental break down.
Due to the fact that Neji was the prodigy in Hyuga clan, they totally forgot about Hinata, they even abandoned her. If It wasn't for Sakura, Hinata would be homeless, or she would have to live in an orphanage. After girls started to live together, they were almost inseparable. They trained with each other at least 5 times a week, and went on almost all missions together.
But there was a mission that Tsunade sent only team 7, Hinata at that time was training with her team. And on that one mission, they founded two girls, and decided to take them back to Konoha. But Sakura didn't know, that those two girls will be the reason why rest of Konoha 12 will left her and Hinata behind.
