Can't Get Passed You (A Haikyuu!! Fanfiction)

Kei Tsukishima is the dark side of the Karasuno boys volleyball team. He's always negative and not enthusiastic at all. Plus, he loves to pick fights with Tobio Kageyama, the team's best setter, and his partner in crime, Shouyo Hinata. No one can seem to get passed Tsukki's blocks when they battle him at the net, (except Hinata ;)), so it's kind of ironic when no one can get passed the iron walls around his heart. Tadashi Yamaguchi has gotten close, but not one person has successfully opened him up. Then a new student comes to Karasuno. Mika Aoyanagi transferred from Date Tech to Karasuno after her brother, Jin, suggested it after they moved into the area. Being at 180 cm (5' 11"), she played for their girls' volleyball team at Date Tech but when she took one look at the girls' team of her new school, she went and joined the boys' volleyball team instead. Her hair already being short she looked like a guy enough to fool the refs. At first, Tsukki doesn't care, but will one missed block set him on the course of his walls coming down?
