Let's get straight to the point, Asuma forgot about his 3 year anniversary with Kurenai and well, Kurenai was upset and very much pissed. You're Asuma's little sister and your 17, the same age as Ino, Sakura, Tenten, Temari, Naruto, Sasuke, Shikamaru, Choji, Kiba, Shino, Lee, Neji, Gaara and Kankuro. Speaking of them, they were at Asuma and Kurenai's shared apartment for who knows what reason.
Asuma was panicking and hyperventilating while you were sitting on the couch, laughing your ass off at his expressions. Ino was laughing with you and Hinata was just giggling. You were good friends with the two girls since they often came to Asuma and Kurenai's shared apartment a lot. And obviously you live there to. You also knew Kiba, Shino, Choji and Shikamaru because they obviously came around. You were basically best friends with Choji and close friends with Kiba, Shino and Shikamaru.
Asuma: "Dammit, stop laughing!!" He said in a panicked and annoyed expression.
