Sakura Haruno was known as the most useless shinobi to ever live, she was an orphan, her parents died a long time ago and she was the last member of the Haruno clan, a clan not many people knew about, they were somewhat mysterious, and the truth about them was hidden. Only the third Hokage, Hiruzen Sarutobi knew about them.
Hinata Hyuga, the ex-heiress of the Hyuga clan, a well-known failure, was weak, useless, shy, timid, no appealing qualities, to anyone! Or so that's what everyone thought, she admitted every single of her failures and had zero self-confidence. Her father pushed her to her limits and his constant shouting and beatings, took every single bit of confidence she gained over the years, in one go.
