In a world training future heroes, Yn stands apart—not because she wants to, but because no one dares get close. Cold, controlled, and terrifyingly precise, she fights like a flawless storm, showing no emotion and no hesitation. She doesn’t care about being a hero, which only makes her more dangerous. Everyone avoids her. Everyone except Katsuki Bakugo. What starts as caution turns into curiosity, then something harder to name. Because Yn doesn’t break, doesn’t slip, doesn’t feel—at least not where anyone can see. And the more Bakugo watches, the more he realizes— the scariest thing about her isn’t her power. It’s how little she seems to need a reason to use it.
