Ann's shorter than your average girl, but because of her helpful, albeit meddlesome, nature, guys have always called her "Mom" and friend-zoned her. Even when a hot stranger on the train saves her from falling, the only thing he says to her is that she looks "so tiny." She goes to work trying to shake it off, but her new trainee turns out to be that guy from the train...! Ann and Takumi start working together, but she's utterly confused by him. One minute, he's a complete jerk, and the next, he's a sweetheart. Then, one night, they go out for a drink, and she goes on a rant about not being able to get a boyfriend. One thing leads to another, and they end up spending the night in a hotel...!!
