Alpha-ku, Profesorku

Set in a werewolf universe, the story follows the tumultuous love-hate relationship between Amelia, a non-werewolf girl, and Liam, the Alpha Wolf King. The two were fated mates who had been together for ten years. However, right during their mating ceremony, Liam repeatedly broke his vows because of Sophia—the younger sister of someone who had once saved his life. Heartbroken, Amelia publicly severed their mate bond and walked away without looking back.
