You have a crush on Kiba Inuzuka. And it didn't go unnoticed. So, instead of being embarrassed, you embraced it. You'd follow him everywhere he'd go (except the bathroom and his house) and embrace your liking towards him. He noticed it very well, and it amused him for a while. But eventually, he grew tired of it. Every time you showed affection and gave him a gift, he would reject it or throw it to the side.

Not only did you noticed, but you and Kiba's friends did. Such as Naruto, Sasuke, Shikamaru, Choji, Lee, Neji, Shino, Gaara, Kankuro, Temari, Sakura, Ino, Tenten and Hinata. You felt hurt, but continued. But one day, you grew tired of trying. You've been trying for 2 years, and nothing. So, you gave up.
