This is a great story about an omega that is taken for an alpha because he works hard and does everything he can to shake off the omega image. His best friend is a beta, who has always been with him through his life and loves him and sees him as a person. Suddenly, the new vice president at his work is his fated pair. His fated pair claims words of love while being with other omegas, and soon we have a love triangle. It's really an interesting story.
