Being a beta in a world where alphas and omegas were destined for each other, Azuma had long accepted that there was no such thing as 'fate' for him. Still trying to get over a heartache from the past, he meets 'Mahoro' by chance one Christmas night. Pitying Mahoro's unfortunate state, Azuma tries to offer help, despite being flustered. While Mahoro refuses Azuma's offer to stay at his house, he invites the latter to drop by his workplace as thanks. It turns out that Mahoro works in a brothel. As Azuma gets more drawn to Mahoro, he finds out that Mahoro is looking for someone: his fated partner. Against his better judgment, Azuma decides to help Mahoro.
