Takasu Ryūji, at first glance, appears to look like a brute and it's because of this most people fear him. Due to this he spends most of his time secluded from his classmates. When Ryūji finds himself in the same class as his secret crush, Kushieda Minori, he enters into an odd alliance with Minori's close friend, Aisaka Taiga. As long as Ryūji promises to help get Taiga closer to her secret crush who also happens to be his best friend, Taiga will help Ryūji get closer to Minori. But, like Ryūji, Taiga is often misunderstood and her fierce and violent outward nature hides her more gentle disposition. Ryūji and Taiga soon find that the more time they spend together, the less their outward appearances hold true. Ryūji and Taiga's lives keep getting tangled together in many interesting ways.
