My thoughts are number 2

Perhaps the most ridiculous of Fanon I think Pairing SasuKarin. I still do not understand how it took Pairing fans who truly believe in what SasuKarin become canon. Until then you are funny.
I decided to show a figure as Karin sees Sasuke and Sakura. I think it was shown in the manga and not just the difference between feelings for Sasuke with Karin and Sakura. His first girl his fan and second fan really loves and wants to earn his respect. Therefore, in the manga was also illustrates the difference in the reaction of Sasuke.
