Kageyama Tobio is the university's untouchable "Ice Prince", effortlessly attractive, intensely focused, and completely emotionally detached. He dates whoever asks, but his relationships always end the same way: with an ex screaming that he's a heartless robot who treats romance like a checklist. Kageyama genuinely believes he's just not built for the game.
But he has a massive blind spot.
For ten years, Hinata Shouyo has been right there, acting as his bright, reliable childhood best friend while silently harboring a painful, secret crush. When an infuriated ex points out that Kageyama's heart is "already occupied," the ice begins to thaw. But just as Kageyama starts turning his intense focus toward his best friend, a campus rival steps in to pursue Hinata, forcing Kageyama's fiercely guarded possessiveness to violently erupt.
