Kousuke may be an omega, but he's a tough, blue-collar worker. He lives with his mate Haruka, a gentle alpha who works as a writer and stays home to care for their family, Kousuke and their two children, Marin and Yosuke. Being an omega, juggling work, housework, and parenting... life isn't always easy or fair. Even so, their days are filled with joy and warmth because Haruka, his one and only mate, showers him with endless love every single day.
