I became the only OMEGA within my group

Kim Sunwoo is a Korean pop singer! he has grown to love singing and dancing, he chooses to peruse his dreams on becoming an idol to influence the well being of others! what a good boy, right? There's only one thing that he must hide. He is an Omega. Idols must be an alpha or beta in order to become an idol in their world, otherwise there can be a very big deal amongst the industry. Kim Sunwoo, or known as, Sunoo, unfortunately was born an Omega but when he suddenly gets accepted to join the boy group ENHYPEN, what will he do??
