A gender test that affects your entire life. The α, β, and Ω genders, which exist separately from men and women, also separate social status. Yuka takes a gender test and is faced with the fact that he is the only one among his friends who is an Omega. Yuka is isolated in class and afraid of her alpha friend, Oga, so he hides the fact that he is an Ω. However, when he saw her childhood friend Kaoru rushing into the nurse's office, he realized that the calm and plain Kaoru had the same Ω-sexuality as him...? [In addition to 13 pages of original comics, it also includes 4 pages of electronic-only manga depicting Kaoru's conflicts.]
