Romantic ga Niawanai

Yoki, an Omega who can’t produce pheromones, becomes captivated by a “fated scent” from a secondhand T-shirt—only to discover it belongs to Mochimaru, a gloomy and far-from-ideal Alpha. Despite finding him unromantic and abrupt (even asking to become mates immediately), Yoki is overwhelmed by instinct and ends up physically involved with him. As Yoki struggles with the aftermath, Mochimaru grows increasingly obsessive and reveals he considers himself a “defective Alpha.”
