Toxic but that's what i loved

Sion Juan was a dominant omega who always managed to control his pheromone. Even people around him barely realized his real trait, including Lexa, a dominant alpha from a powerful family. But once they got close, Lexa could smell Sion's pheromone. And weirdly, Lexa, who was never attracted to omega's pheromones, can't help but lose control of his alpha instinct. They began their uncommon relationship as sex partners. But for Sion, it started to be more than just that. But it was all too late. Lexa loved someone else, and Sion had no choice but to be gone from his life. With his little baby, he knew he would be just fine.
