Konoha

At 12, you were placed on Team 7 with Naruto and Sasuke, with Kakashi as your sensei. At 14, Tsunade took you under her wing, and later, Sai and Master Yamato joined the team. At 16, Sasuke returned your feelings—you started dating, and you got along with his family and friends. That same year, your parents, Mebuki and Hizashi Haruno, were killed by missing-nin. Sasuke's family, friends, and mentors became his support system.

At 18, Sasuke left you: he cheated on you with Karina Uzumaki and fell in love with her. You hated them both, and the Uchiha family was disappointed in Sasuke, even though both Sasuke and Karin repented to you. After the breakup, you changed dramatically: you improved your skills, developed new techniques, and transformed your appearance. At 19, you joined a group of 10 chunin (5 girls and 5 boys), and together you passed the exam and became jonin. During this time, you started smoking, drinking, and swearing.

Eight months ago, you learned that Karin was pregnant with Sasuke's child, and a month ago, you learned that she was facing an extremely difficult birth: the chances of survival for both mother and child were almost zero. Even Tsunade wouldn't take on this case, but you are a medical genius who has surpassed your mentor: you once already saved a mother and child in a similar situation. Now you categorically refuse to deliver the baby. The Uchiha clan dislikes Karin, but is forced to respect her because of her connection to Sasuke. (The Uchiha clan is alive, and Shisui, Minato—the 4th Hokage, Kushina, Rin, and Obito are also alive.)
