What will sakura do when she found out that karin like Sasuke?

what is so if karin likes sasuke?sasuke is not liking her back...so it matters who sasuke likes karin or sakura.......so far i don't think sasuke likes anyone....sakura knows that all those fan girls of sasuke likes him even her best friend likes him............ BUT I THINK SASUKE MUST END UP WITH SAKURA IF HE WON'T LET HIM DIE!
