Despite being a beta in a world where alphas and omegas were predetermined to be together, Azuma had always believed in the concept of free will. However, after experiencing heartbreak from a past relationship, he found it difficult to accept that fate had no role in his life. One Christmas night, while trying to move on, Azuma encountered Mahoro by chance. Feeling sorry for her unfortunate circumstances, he tried to offer assistance, despite feeling overwhelmed. Although Mahoro declined his invitation to stay at his home, she gratefully accepted his offer to visit his workplace as a token of appreciation. To Azumas surprise, Mahoro worked in a brothel. As he grew more attracted to her, Azuma discovered that Mahoro was searching for someone: her fated partner. Despite his reservations, Azuma decided to assist her in finding her soulmate.
