Addictions due to Taste
Many people knew that taste could make people addicted to the weirdest things with little or no explanation. The people of Konoha knew first hand that taste could make two complete opposites addicted to each other in a matter of seconds. They knew this because Sasuke Uchiha and Naruto Uzamaki were the perfect example of how taste could get you addicted to something and there would be no explanation for it. Everybody had first found out that they were dating when they saw them kissing at Ichiraku's ramen shop. After everybody found out the two were seen making out everywhere and often had to be pulled apart before they went too far in public. Nobody, including the two, could think of an explanation as to why they were so addicted to the way each other tasted. But everybody could see that they were in love so nobody was surprised when the two announced that they were going to get married. After all everybody knew that once the two had found that certain addiction they would never get over it.
