Hinata had always loved Naruto as long as she could remember. She even told him her feelings during the invasion of Pain. Even though she didn't get a response she still loved him. She was blinded by the unrequited love she had for him. Until one day she had enough, enough of everything. As the heir of the Hyuga clan, she was always branded weak, incompetent, worthless, a disgrace and foolish, always compared to her little sister and cousin. Her love for Naruto kept her going but when she had realized how she meant nothing to Naruto, to anyone.
She snapped. She wanted to please everyone but nothing seemed to please them.
Now it was her turn to satisfy herself. She wanted to show them that she was not weak and indeed powerful. She would show everyone who foolishly and stupidly judged her. She grabbed a knife and made a cut on her right palm, leaving a scar which symbolizes her promise of becoming stronger and to put herself before others.
The next day she went to the Hokage, Lady Tsunade.
She asked permission to leave Konoha and return when she felt the time was right. She would return back to the village.
"Hinata, have you discussed this matter with your father?" the blonde grunted.
Bowing Hinata said, "No, I'm already a disgrace in his eyes. Why would I even bother!? Please! Lady Hokage, grant my request"
The Lady Hokage was shocked for it was the first time Hinata did not stutter. She sensed the seriousness and importance of the request from the tone of the Hyuga heiress.
"Alright! I approve of your request. "I want you to accomplish whatever you want to achieve", said the blonde smirking.
"Hai! Arigato, Lady Hokage Tsunade-sama!" Hinata replied.
Then she went out of her office. Returning back to the mansion to gather her materials needed.
