Collision Course (Keishin Ukai x Reader)
15 parts Ongoing Y/N Akagi never expected to spend her mornings locked in a battle of wits with Karasuno's hotheaded volleyball coach over something as trivial as gym space. But one scheduling conflict turns into a full-blown war, and soon, neither of them can step into the faculty lounge without sparks flying.
Keishin Ukai thinks Y/N is the most frustrating woman on the planet-condescending, stubborn, and way too confident in her opinions about his so-called "childish" coffee preferences. But somehow, she gets under his skin in a way no one else does, and he hates how much he likes riling her up.
Between heated arguments, lingering glances, and an entire faculty placing bets on when they'll crack, their rivalry starts shifting into something else-something neither of them is ready to name.
It's a battle of wills, but gravity has a funny way of pulling two people together, no matter how hard they resist.
