You Like Me, Not My Daughter?! (Manga) Vol. 1  (English, Paperback, Nozomi Kota)

When Ayako's sister died, leaving her young daughter all alone, Ayako stepped up and took the child into her life. Now that her niece/adopted daughter is a teenager, a 30-something Ayako can sense first love in the air. Ayako teases her daughter about Takumi, their handsome and college-aged neighbor, who's been tutoring her since she was young--could they be a blossoming couple, since he's always beaming when he comes to their house? To Ayako's surprise, Takumi isn't interested in daughter dearest: he's long had a crush on Ayako herself! In this age gap romantic comedy, one young man is ready to bring a little sugar to the sexy mom next door.
