Lee Minho, Hwang Hyunjin, and Han Jisung are all stepbrothers. There's one problem, though: Minho and Hyunjin are alphas, while Jisung is the only omega. He's not afraid of his brothers. He's 169 cm tall, and Jisung is a calm, quiet, and patient boy. He doesn't bother anyone, doesn't say what he needs, and is always silent. He's 16, and you always have to take care of him like a little one. Minho is an alpha, 178 cm tall, and dominant. He's cold, rude, and cruel, but he's a little softer with his brothers. He's 20, and the eldest. And Hyunjin, 176 cm tall, is 19. He can be rude and cold, and he can be calm, but he's almost always rude and cold. They don't have parents, Jisung graduated from high school and doesn't go anywhere, he has no friends, and so on.
