IB

Some chemistry is impossible to ignore. Unfortunately for Y/N, hers has a name. Augustus Black. Regulus Black’s dangerously charming older brother has almost-black curls, grey-blue eyes, an infamous reputation, and the irritating confidence of someone who has spent his entire life knowing exactly what effect he has on people. One encounter at The Serpent’s Eve, Slytherin’s infamous opening party, is enough to leave Y/N curious. A few lingering looks make it worse. Then an Advanced Magic practicum reveals something neither of them expected: Y/N and Augustus possess one of the strongest magical compatibility readings Hogwarts has recorded in decades. Suddenly, attraction has become magical theory. Their friends are taking bets. Rumors are spreading through the castle. Professors are concerned about something called a Resonance Bond. And everyone seems determined to decide what the connection means before Y/N and Augustus have figured it out themselves. But magical compatibility isn’t destiny. And it certainly doesn’t explain everything. Not the flirting. Not the jealousy. Not the way a crowded room suddenly feels considerably smaller when Augustus Black walks into it. Perhaps it’s magic. Perhaps it’s all in Y/N’s head. Or perhaps everyone is making this far more complicated than it needs to be. Because sometimes two people simply have really, really good chemistry.
