A beautiful mother, a pining tutor, and romantic hijinks await in this hot mom romcom! Ever since her sister and brother-in-law died in an accident ten years ago, thirty-something-year-old Ayako Katsuragi has been raising her niece Miu as her own daughter. Now that she’s in high school though, Ayako has begun to worry about the boys that might want to date Miu, especially their twenty-year-old neighbor Takumi Aterazawa. But when Takumi says he needs to talk to her, Ayako gets the shock of her life! It’s not Miu he’s got feelings for, it’s her! Will Ayako be able to overcome her doubts and give his love a chance?

Thirty-something-year-old Ayako never expected her college-student neighbour, Takumi, to confess that he's in love with her. But now that he has and her attempts to dissuade him have failed, Ayako feels more torn than ever. That is, until her daughter Miu shares some shocking news - Takumi's already moved on to someone new! But if this is the development Ayako's been waiting for, then why does she feel so upset? And why is she spying on him while he's on a date with his new flame?!

It’s no secret that Ayako believes she’s too old to entertain the advances of her college-age neighbour, Takumi. And when Takumi and Ayako finally go on their first date, she can’t help but feel like all eyes are on her. After all, she’s spending the day at an amusement park with a man more than ten years her junior! She’s still not sure how to handle his fervent affection…but when a series of disasters leads to a night spent together in a hotel room, will Ayako finally be able to admit she’s falling–just a little?

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.
