Ookami Kodomo no Ame to Yuki

When Hana worked up the courage to speak to the mysterious loner in her college class, she never expected the encounter would blossom into true love-nor that he was secretly a wolf living in human form. Their relationship was far from ordinary, but she wouldn't have had it any other way. Her joy only grows with the births of Ame and Yuki, who have inherited their father's unique ability to transform. But life is full of both joy and hardship, and Hana is left to bring up her little wolves on her own. Raising human children is hard enough... but how will she handle their wild side, too?
