But when he faces off with Megumi, he's finally met his match-just not in the way he thinks!

Megumi, the son of the elite school's chairman, takes it upon himself to avenge his pummeled friends, but when the time comes, all he finds is a fired-up Tsugumi reeking of pheromones and insisting he can control his heat through sheer willpower! Faced with a different kind of battle, Megumi goes from attacker to savior, whisking Tsugumi to safety and leaving the cranky omega reconsidering everything he's ever thought about alphas.
