After moving to Japan with her military family, American Y/N starts at Aoba Johsai High and is given a tour by the student council president. When they stop by the volleyball gym, she catches the attention of Oikawa Tooru—and it’s love at first sight. From that moment on, Oikawa becomes determined to get her attention, constantly finding excuses to talk to her, impress her, and spend time with her. Before long, his shameless flirting turns into his own not-so-subtle attempts at dating her. Unfortunately for Oikawa, Y/N has no idea just how serious he is about her.
