Musume ja Nakute Mama ga Suki nano!?

A decade ago, Ayako took in her orphaned niece, Miu, as her own. They now share a close mother-daughter bond, but being a young single mom hasn't been easy for Ayako. Good thing Miu's childhood friend Takumi has been there for the family every step of the way. After all these years, he's grown into a kind, handsome young man—just the kind of guy Ayako would like to see Miu date. In fact, when Takumi asks to speak with Ayako privately one day, she can't wait to give the young couple her blessing. But little does she know it's not Miu that Takumi has fallen for... It's her! How will Ayako handle the romantic feelings of the boy who's meant so much to her family? And what will it all mean for her relationship with her daughter?
