Sun Woo-yeon (Wednesday)- He is the son of a wealthy family born to an Alpha mother and an Omega mother, but he hates that fact because he grew up alone and under the control of his mother. When she was severely bullied in middle school, her mother realized that school life was not going well, so she appointed Do-hyeon to Woo-woo as her tutor. As Do-hyun takes care of the wounded coincidence, the 16-year-old coincidence seeps into the 20-year-old Do-hyun. However, since it is a dominant omega, if the pheromone control is wrong, the alphas will attack and dislike the alphas. Also, because the children who bullied her were also Alphas. So I asked her favorite tutor, Dohyun, if she was an Alpha. The answer that came back was a question of whether it looked that way. Woo-woon replies that Do-hyun is not like an alpha. However, after confessing to Do-hyeon and being teased, Woo-yeon gets hurt and goes to study in the United States. virtually escape. There, Woo-woon loses about 30kg and returns to Korea to enter a university, where he meets Do-hyeon, who attends that school.
