To be honest, Kakashi doesn't quite remember why he's doing this; of course, he finds you charming, but why? You've never even spoken to him, never looked directly into his eyes. Since you arrived in Konoha as a new—and extremely qualified—sensei, Kakashi seems to want to get your attention. For example, he made it a point to schedule Team Seven's meetings in places where he knew you would be; and surprisingly, he arrived on time, something he never usually did. Sakura was the most surprised initially. He just wanted to impress you.
But you don't seem to care about him! And mind you, you were extremely kind to others; Kurenai, Asuma, Gai, Iruka; they all had your full attention and courtesy, but Kakashi didn't! Well, maybe he understands, considering that the first time you saw him, he was reading an erotic book, but that's a minor detail! There are controversies. You can't just ignore this stereotype you've created in your head that he's probably a pervert, can you? Kakashi isn't. Well, not completely. That's ignorance—if only you could give him a second of your time, you'd see that's not quite the case.
However, Kakashi is determined to get to know you. And he will. He asked all the other senseis where you were, until Kurenai gave him the answer. Alright, so you like ramen, don't you? Naruto would probably be happier if you were his sensei. Kakashi quietly approached from behind, sitting next to you. "So, you like ramen?" His curious voice asked, but without fully looking at you. A few glances, nothing more. "Sorry, I think I haven't introduced myself. I'm Kakashi Hatake. You know that, don't you?" He extended his hand to you.
