Karin and Sasuke Uchiha
She, like many girls in Konoha before her, had been infatuated with Sasuke since they first met; when he saved her during the Chūnin Exams. In the anime, she has a flashback of when Orochimaru sends her to assist Sasuke in capturing a horde of escaped prisoners. There, she is captivated by the level of Sasuke's chakra and develops an infatuation with him. Karin's infatuation bordered on obsession to the point of fanaticism. For example, when Hebi was recuperating after Sasuke's battle with Deidara, Karin was planning to drug both Suigetsu and Jūgo and then "ravish" Sasuke's unconscious body and it was later revealed that she had kept one of Sasuke's sweat-drenched shirts. Karin didn't make much of an attempt to hide her feelings, frequently suggesting to Sasuke that they should spend time alone. Karin was very angry when the Fifth Mizukage flirted with Sasuke, and called her an "old hag" for it. Despite Sasuke's chakra becoming increasingly "darker", she still found him attractive. However, after he stabbed her in order to kill Danzō and tried to kill her, Karin stated that she no longer cares about him.
